Perhaps you should try some spelling variations:
choon chuan » chen chuan
chuan huang » yuhuan huang, chuan bang
wang yang » wang yan, wang liang, wang yanling
yan liang » yang liang, wang liang, you liang
cheng hei » chen wei, cheng han, chen lei
yi liang » you liang, _ liang, li qiang
cheng yi » cheng y, chong yi, cheng sim

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yi liang) OR (yan liang)) choon chuan huang ((cheng yi) OR (cheng hei)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yi liang) or (yan liang)) choon chuan huang ((cheng yi) OR (cheng hei)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yi liang) or (yan liang)) choon chuan huang ((cheng yi) OR (cheng hei)) ;*.
