Question: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.

Zheng He's sailing charts, the Mao Kun map, were published in a book entitled the Wubei Zhi (A Treatise on Armament Technology) written in 1621 and published in 1628 but traced back to Zheng He's and earlier voyages. It was originally a strip map 20.5 cm by 560 cm that could be rolled up, but was divided into 40 pages which vary in scale from 7 miles/inch in the Nanjing area to 215 miles/inch in parts of the African coast. Investigation into folios 19V to 20R of the Mao Kun Map which covers the Indian Ocean including the South India, Sri Lanka, the Maldives, and East Africa suggests that it is a composite of four maps, one for Sri Lanka, one for South India one for the Maldives and one for around 400 km of the East African coast, no further south than 6 degrees south of the Equator. Each of these maps is positioned at a different orientation to fit with the ocean currents and winds required of a sailing chart, rather than a formal map. The analysis also suggests that Arabic-speaking pilots with a detailed knowledge of the African coast were involved in the cartography. There is little attempt to provide an accurate 2-D representation; instead the sailing instructions are given using a 24-point compass system with a Chinese symbol for each point, together with a sailing time or distance, which takes account of the local currents and winds. Sometimes depth soundings are also provided. It also shows bays, estuaries, capes and islands, ports and mountains along the coast, important landmarks such as pagodas and temples, and shoal rocks. Of 300 named places outside China, more than 80% can be confidently located. There are also fifty observations of stellar altitude.

Question: The Sinhalese (Sinhala: siNhl jaatiy Sinhala Jathiya, also known as Hela) are an Indo-Aryan-speaking ethnic group native to the island of Sri Lanka. They constitute about 75% of the Sri Lankan population and number greater than 16.2 million. The Sinhalese identity is based on language, historical heritage and religion. The Sinhalese people speak the Sinhalese language, an Indo-Aryan language, and are predominantly Theravada Buddhists, although a small percentage of Sinhalese follow branches of Christianity.

The Sinhalese speak Sinhala, also known as "Helabasa"; this language has two varieties, spoken and written. Sinhala is an Indo-Aryan language within the broader group of Indo-European languages. The language was brought to Sri Lanka by the ancestors of the Sinhalese from northern India who settled on the island in the 6th century BCE. Sinhala developed in a way different from the other Indo-Aryan languages because of the geographic separation from its Indo-Aryan sister languages. Sinhala was influenced by many languages, prominently Pali, the sacred language of Southern Buddhism, and Sanskrit. Many early Sinhala texts such as the Hela Atuwa were lost after their translation into Pali. Other significant Sinhala texts include Amavatura, Kavu Silumina, Jathaka Potha and Sala Liheeniya. Sinhala has also adopted many loanwords of foreign origin, including from many Indian languages and colonial languages Portuguese, Dutch, and English. Sandesha Kavyas written by Buddhist priests of Sri Lanka are regarded as some of the most sophisticated and versatile works of literature in the world. The Sinhala language was mainly inspired by Sanskrit and Pali, and many words of the Sinhala language derive from these languages. Today some English words too have come in as a result of the British occupation during colonial times, and the exposure to foreign cultures through television and Hollywood movies. Additionally many Dutch and Portuguese words can be seen in the coastal areas. Folk tales like Mahadana Muttha saha Golayo and Kawate Andare continue to entertain children today. Mahadana Muttha tells the tale of a fool cum Pundit who travels around the country with his followers (Golayo) creating mischief through his ignorance. Kawate Andare tells the tale of a witty court jester and his interactions with the royal court and his son. In the modern period, Sinhala writers such as Martin Wickremasinghe and G. B. Senanayake have drawn widespread acclaim. Other writers of repute include Mahagama Sekera and Madewela S. Ratnayake. Martin Wickramasinghe wrote the immensely popular children's novel Madol Duwa. Munadasa Cumaratunga's Hath Pana is also widely known.
