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
yi liang » you liang, _ liang, li qiang
cheng yi » cheng y, cheng hei, cheng sim
chong yi » chong yah, chong yun, hong yu

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 (chong yi)) ;~.
• 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 (chong yi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yi liang) or (yan liang)) choon chuan huang ((cheng yi) OR (chong yi)) ;*.
