Perhaps you should try some spelling variations:
chung kang » chan kang, chung kay, chung tong
yuan ming » yuan ting, kian ming, tuan minh
yun jang » suk jang, yun song
kong siu » kong eiu, wong siu, dong sin
wan yan » wang yan, nan yan, wai yan
dong di » dong sin
ya yuan » yan yuan

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 (dong di)) ya yuan ming ((yun jang) OR (chung kang)) kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong di)) ya yuan ming ((yun jang) or (chung kang)) kong siu ;*.
