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. Its common name derives from the large amount of silt it contains, which is deposited in a densely populated 2,700-square-mile delta on the Gulf of Tonkin.
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.
Although Uncle Sam is one of our most familiar icons, many Americans have little or no concept of his origins. If pressed, the average American might point to the early twentieth century and Sam's frequent appearance on army recruitment posters. In reality, however, the figure of Uncle Sam dates back much further. Uncle Sam is the culmination of a tradition of representative male icons in America which can be traced well back into colonial times. The actual figure of Uncle Sam, however, dates from the War of 1812.
