Locally called the Song Hong, it arises is the central Yunnan province, and is joined by the Song Li and Song Da (or Clear and Dark Rivers) on its way to the sea.

Uncle Sam (initials U.S.) is a common national personification of the American government or the United States in general that, according to legend, came into use during the War of 1812 and was supposedly named for Samuel Wilson. Its actual origin is obscure. Uncle Sam represents a manifestation of patriotic emotion.
The connection between the popular cartoon figure and Samuel Wilson of Troy, NY was reported in the New York Gazette on May 12, 1830, and later confirmed by Samuel Wilson's great-and great-great-nephews. By the early twentieth century, there was little physical resemblance left between Samuel Wilson and Uncle Sam. As a symbol of an ever-changing nation, Uncle Sam had gone through many incarnations. Initially cartoon versions of Sam were very familiar to those of Brother Jonathan.
