Answer 1

Most of these languages are not related to one another within the last 10,000 years. Mandarin, Cantonese, Shanghainese, and Tibetan are related to one another within the Sino-Tibetan language family. The first three of these are more closely related to one another within the Sinitic branch of Sino-Tibetan. The reason some of these languages have similarities is not because they are related to one another, but because of long contact with one another. Whenever languages are in contact for a long period of time, they tend to borrow things from one another.
