Question: What is a staple food in the country that had a large amount of contacts during Yuan with the country that pugs come from?

full_context: Document 1: Tibet: The economy of Tibet is dominated by subsistence agriculture, though tourism has become a growing industry in recent decades. The dominant religion in Tibet is Tibetan Buddhism; in addition there is Bön, which is similar to Tibetan Buddhism, and there are also Tibetan Muslims and Christian minorities. Tibetan Buddhism is a primary influence on the art, music, and festivals of the region. Tibetan architecture reflects Chinese and Indian influences. Staple foods in Tibet are roasted barley, yak meat, and butter tea.
Document 2: History of New Zealand: From 1840 there was considerable European settlement, primarily from England and Wales, Scotland and Ireland; and to a lesser extent the United States, India, China, and various parts of continental Europe, including the province of Dalmatia in what is now Croatia, and Bohemia in what is now the Czech Republic. Already a majority of the population by 1859, the number of Pākehā settlers increased rapidly to reach over one million by 1916.
Document 3: Dog fighting: Despite periodic dog - fight prosecutions, illegal canine pit battles continued after the Cruelty to Animals Act 1835 of England and Wales. Sporting journals of the 18th and 19th centuries depict the Black Country and London as the primary English dog fight centers of the period.
Document 4: Tibet: The main crops grown are barley, wheat, buckwheat, rye, potatoes, and assorted fruits and vegetables. Tibet is ranked the lowest among China’s 31 provinces on the Human Development Index according to UN Development Programme data. In recent years, due to increased interest in Tibetan Buddhism, tourism has become an increasingly important sector, and is actively promoted by the authorities. Tourism brings in the most income from the sale of handicrafts. These include Tibetan hats, jewelry (silver and gold), wooden items, clothing, quilts, fabrics, Tibetan rugs and carpets. The Central People's Government exempts Tibet from all taxation and provides 90% of Tibet's government expenditures. However most of this investment goes to pay migrant workers who do not settle in Tibet and send much of their income home to other provinces.
Document 5: Tibet: Tibet has various festivals that are commonly performed to worship the Buddha[citation needed] throughout the year. Losar is the Tibetan New Year Festival. Preparations for the festive event are manifested by special offerings to family shrine deities, painted doors with religious symbols, and other painstaking jobs done to prepare for the event. Tibetans eat Guthuk (barley noodle soup with filling) on New Year's Eve with their families. The Monlam Prayer Festival follows it in the first month of the Tibetan calendar, falling between the fourth and the eleventh days of the first Tibetan month. It involves dancing and participating in sports events, as well as sharing picnics. The event was established in 1049 by Tsong Khapa, the founder of the Dalai Lama and the Panchen Lama's order.
Document 6: Tibet: The most important crop in Tibet is barley, and dough made from barley flour—called tsampa—is the staple food of Tibet. This is either rolled into noodles or made into steamed dumplings called momos. Meat dishes are likely to be yak, goat, or mutton, often dried, or cooked into a spicy stew with potatoes. Mustard seed is cultivated in Tibet, and therefore features heavily in its cuisine. Yak yogurt, butter and cheese are frequently eaten, and well-prepared yogurt is considered something of a prestige item. Butter tea is very popular to drink.
Document 7: Sino-Tibetan relations during the Ming dynasty: Laird writes that the Ming appointed titles to eastern Tibetan princes, and that "these alliances with eastern Tibetan principalities are the evidence China now produces for its assertion that the Ming ruled Tibet," despite the fact that the Ming did not send an army to replace the Mongols after they left Tibet. Yiu Yung-chin states that the furthest western extent of the Ming dynasty's territory was Gansu, Sichuan, and Yunnan while "the Ming did not possess Tibet."
Document 8: Sino-Tibetan relations during the Ming dynasty: Wang and Nyima argue that the Ming emperor sent edicts to Tibet twice in the second year of the Ming dynasty, and demonstrated that he viewed Tibet as a significant region to pacify by urging various Tibetan tribes to submit to the authority of the Ming court. They note that at the same time, the Mongol Prince Punala, who had inherited his position as ruler of areas of Tibet, went to Nanjing in 1371 to pay tribute and show his allegiance to the Ming court, bringing with him the seal of authority issued by the Yuan court. They also state that since successors of lamas granted the title of "prince" had to travel to the Ming court to renew this title, and since lamas called themselves princes, the Ming court therefore had "full sovereignty over Tibet." They state that the Ming dynasty, by issuing imperial edicts to invite ex-Yuan officials to the court for official positions in the early years of its founding, won submission from ex-Yuan religious and administrative leaders in the Tibetan areas, and thereby incorporated Tibetan areas into the rule of the Ming court. Thus, they conclude, the Ming court won the power to rule Tibetan areas formerly under the rule of the Yuan dynasty.
Document 9: Sino-Tibetan relations during the Ming dynasty: Patricia Ebrey writes that Tibet, like Joseon Korea and other neighboring states to the Ming, settled for its tributary status while there were no troops or governors of Ming China stationed in its territory. Laird writes that "after the Mongol troops left Tibet, no Ming troops replaced them." Wang and Nyima state that, despite the fact that the Ming refrained from sending troops to subdue Tibet and refrained from garrisoning Ming troops there, these measures were unnecessary so long as the Ming court upheld close ties with Tibetan vassals and their forces. However, there were instances in the 14th century when the Hongwu Emperor did use military force to quell unrest in Tibet. John D. Langlois writes that there was unrest in Tibet and western Sichuan, which the Marquis Mu Ying (沐英) was commissioned to quell in November 1378 after he established a Taozhou garrison in Gansu. Langlois notes that by October 1379, Mu Ying had allegedly captured 30,000 Tibetan prisoners and 200,000 domesticated animals. Yet invasion went both ways; the Ming general Qu Neng, under the command of Lan Yu, was ordered to repel a Tibetan assault into Sichuan in 1390.
Document 10: Cavalier King Charles Spaniel: The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club. It originated in the United Kingdom and is one of the more popular breeds in many countries. Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure - breed in the United States (2013 Registration Statistics). It has a silky, smooth coat and commonly a smooth undocked tail. The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black / white / tan), Black and Tan, and Ruby. The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction. Since they are a family dog, it is recommended to not leave them alone for long periods at a time. The expected average lifespan of a Cavalier King Charles Spaniel is under ten years.

Document 12: Pug: Pugs were brought from China to Europe in the sixteenth century and were popularized in Western Europe by the House of Orange of the Netherlands, and the House of Stuart. In the United Kingdom, in the nineteenth century, Queen Victoria developed a passion for pugs which she passed on to other members of the Royal family.
Document 13: Sino-Tibetan relations during the Ming dynasty: The late Turrell V. Wylie, a former professor of the University of Washington, and Li Tieh-tseng argue that the reliability of the heavily censored History of Ming as a credible source on Sino-Tibetan relations is questionable, in the light of modern scholarship. Other historians also assert that these Ming titles were nominal and did not actually confer the authority that the earlier Yuan titles had. Van Praag writes that the "numerous economically motivated Tibetan missions to the Ming Court are referred to as 'tributary missions' in the Ming Shih." Van Praag writes that these "tributary missions" were simply prompted by China's need for horses from Tibet, since a viable horse market in Mongol lands was closed as a result of incessant conflict. Morris Rossabi also writes that "Tibet, which had extensive contacts with China during the Yuan, scarcely had diplomatic relations with the Ming."
Document 14: Tibet: Religion is extremely important to the Tibetans and has a strong influence over all aspects of their lives. Bön is the ancient religion of Tibet, but has been almost eclipsed by Tibetan Buddhism, a distinctive form of Mahayana and Vajrayana, which was introduced into Tibet from the Sanskrit Buddhist tradition of northern India. Tibetan Buddhism is practiced not only in Tibet but also in Mongolia, parts of northern India, the Buryat Republic, the Tuva Republic, and in the Republic of Kalmykia and some other parts of China. During China's Cultural Revolution, nearly all Tibet's monasteries were ransacked and destroyed by the Red Guards. A few monasteries have begun to rebuild since the 1980s (with limited support from the Chinese government) and greater religious freedom has been granted – although it is still limited. Monks returned to monasteries across Tibet and monastic education resumed even though the number of monks imposed is strictly limited. Before the 1950s, between 10 and 20% of males in Tibet were monks.
Document 15: Sino-Tibetan relations during the Ming dynasty: Dawa Norbu argues that modern Chinese Communist historians tend to be in favor of the view that the Ming simply reappointed old Yuan dynasty officials in Tibet and perpetuated their rule of Tibet in this manner. Norbu writes that, although this would have been true for the eastern Tibetan regions of Amdo and Kham's "tribute-cum-trade" relations with the Ming, it was untrue if applied to the western Tibetan regions of Ü-Tsang and Ngari. After the Phagmodrupa Changchub Gyaltsen, these were ruled by "three successive nationalistic regimes," which Norbu writes "Communist historians prefer to ignore."
