Question: Hokkien /hkin/ (traditional Chinese: ; simplified Chinese: ; pinyin: Fujianhua; Peh-oe-ji: Hok-kian oe) or Quanzhang (QuanzhouZhangzhou / ChinchewChangchew; BP: ZuanziuZiangziu) is a group of mutually intelligible Min Nan Chinese dialects spoken throughout Southeast Asia, Taiwan, and by many other overseas Chinese. Hokkien originated from a dialect in southern Fujian. It is closely related to the Teochew, though mutual comprehension is difficult, and is somewhat more distantly related to Hainanese. Besides Hokkien, there are also other Min and Hakka dialects in Fujian province, most of which are not mutually intelligible with Hokkien.

Answer: Where did Hokkien originate?

Question: Sarvastivada teachingswhich were criticized by Nagarjunawere reformulated by scholars such as Vasubandhu and Asanga and were adapted into the Yogacara school. While the Madhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogacara asserted that the mind and only the mind is ultimately real (a doctrine known as cittamatra). Not all Yogacarins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not.[web 11] These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahayana metaphysics in the Indo-Tibetan tradition.

Answer: What teaching were criticized by Nagarjuna?

Question: While the Federal District was ruled by the federal government through an appointed governor, the municipalities within it were autonomous, and this duality of powers created tension between the municipalities and the federal government for more than a century. In 1903, Porfirio Diaz largely reduced the powers of the municipalities within the Federal District. Eventually, in December 1928, the federal government decided to abolish all the municipalities of the Federal District. In place of the municipalities, the Federal District was divided into one "Central Department" and 13 delegaciones (boroughs) administered directly by the government of the Federal District. The Central Department was integrated by the former municipalities of Mexico City, Tacuba, Tacubaya and Mixcoac.

Answer:
When were the powers of the municipalities of Mexico City first reduced?
