Clear: 1, (liquid or gas) is pure without impurities, as opposed to "turbid": pure | clear | clear | clear and bright. 2, silence: quiet | cold and cheerless. 3, fair and honest: clean | innocent | honest official. 4, simple: green tea | cappella | clear soup. Chongqing: sound and form. From the water, Yusheng. Original meaning: The word "water changes from clean to dirty" is extended to "change". Literally, the word "change" has no obvious connection and may be related to special affairs. However, the whole name gives people a kind of aloof and indifferent, like the clear water in early summer or the beautiful countryside, with a light and graceful meaning.
