Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
dean hua » dean a
tuan hua » tuan vu, yuan hui
yang tin » yang jin, yang lin, yang jing
tin hong » tan hong, kia hong, thi hong
hong hai » shang hai, zhong tai, dang hai
tan hua » tan chia, tan puay

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 yan ((((dean hua) OR (tuan hua))) OR (((tan hua) OR (wang hua)))) gain yang tin hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((dean hua) OR (tuan hua))) or (((tan hua) or (wang hua)))) gain yang tin hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((dean hua) OR (tuan hua))) or (((tan hua) or (wang hua)))) gain yang tin hong hai ;*.
