Perhaps you should try some spelling variations:
chung kang » chan kang, chung kay
chung tong » chung chong, chung mona, phung tung
wong shiu » cong shu, song shin, wong sau
wong siu » kong siu, wong sau, wong siew
yan yan » yan yuan, nan yan, yang yang
zi chen » zhi chen, yi chen, li chen
yan zi » yan zhi, yuan zi, ban zi
wang » wing, wan, lang

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 yan zi chen ((chung kang) OR (chung tong)) ((wong siu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yan zi chen ((chung kang) or (chung tong)) ((wong siu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yan zi chen ((chung kang) or (chung tong)) ((wong siu) OR (wong shiu)) ;*.
