Perhaps you should try some spelling variations:
guan chia » tuan china, tan chia
chia dan » chia lan, chia wen, shi dan
dan yang » daun yang, tan yang, wang yang
wan yan » wang yan, nan yan, wang yang
wai yan » wang yan, wei yang
li gang » liu gang, ii gang, i gang
le dang » le sang, le duong
hai » hadi, haji, hari

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: ((wan yan) OR (wai yan)) guan chia dan yang ((li gang) OR (le dang)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (wai yan)) guan chia dan yang ((li gang) or (le dang)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) OR (wai yan)) guan chia dan yang ((li gang) or (le dang)) hai ;*.
