Perhaps you should try some spelling variations:
yeung tang » leung tang
hang ching » hang china, huang chang
tang hang » tang tang, tang zheng, kang han
tong shui » tong hui, cong shu, gong hui
yang jun » yang jui, pang jun, yang jin
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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

• Adding a wildcard symbol may retrieve word variants: yeung tang hang ching kwan ((((yang xi) or (yang yi))) or (yang jun)) tong shui ;*.
