[Q]: Hokkien /hɒˈkiɛn/ (traditional Chinese: 福建話; simplified Chinese: 福建话; pinyin: Fújiànhuà; Pe̍h-ōe-jī: Hok-kiàn oē) or Quanzhang (Quanzhou–Zhangzhou / Chinchew–Changchew; BP: Zuánziū–Ziāngziū) 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.
[A]: Where did Hokkien originate?


[Q]: In the meantime, on August 1, 1774, an experiment conducted by the British clergyman Joseph Priestley focused sunlight on mercuric oxide (HgO) inside a glass tube, which liberated a gas he named "dephlogisticated air". He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it. After breathing the gas himself, he wrote: "The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards." Priestley published his findings in 1775 in a paper titled "An Account of Further Discoveries in Air" which was included in the second volume of his book titled Experiments and Observations on Different Kinds of Air. Because he published his findings first, Priestley is usually given priority in the discovery.
[A]: "An Account of Further Discoveries in Air" was published by who in 1775?


[Q]: In times past, until the 15th century, in Korea, Literary Chinese was the dominant form of written communication, prior to the creation of hangul, the Korean alphabet. Much of the vocabulary, especially in the realms of science and sociology, comes directly from Chinese, comparable to Latin or Greek root words in European languages. However, due to the lack of tones in Korean,[citation needed] as the words were imported from Chinese, many dissimilar characters took on identical sounds, and subsequently identical spelling in hangul.[citation needed] Chinese characters are sometimes used to this day for either clarification in a practical manner, or to give a distinguished appearance, as knowledge of Chinese characters is considered a high class attribute and an indispensable part of a classical education.[citation needed] It is also observed that the preference for Chinese characters is treated as being conservative and Confucian.
[A]:
What was the dominant form of written communication?
