Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
chen zheng » chen zhen, chen aizheng, cheng zhang
zheng wong » zheng rong, zheng cong, zheng song
yan liang » wang liang, you liang, yan wang
wong tong » wong tony, tong song
wang nan » wang yan, wang ban, wang dan
tong hui » wang hui

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang nan ((yan liang) OR (yang liang)) chen zheng wong tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan ((yan liang) OR (yang liang)) chen zheng wong tong hui ;*.
