gain yang » dan yang, daun yang, yin yang
wing yan » wang yan, wing ian, wing tan
tan yang » dan yang, tan ying, tan yong
lin long » lin ling, lin zong, pain long
han hua » wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia

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: wing yan ((han hua) OR (tan hua)) ((gain yang) OR (tan yang)) lin long grain ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((han hua) or (tan hua)) ((gain yang) OR (tan yang)) lin long grain ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((han hua) or (tan hua)) ((gain yang) OR (tan yang)) lin long grain ;*.
