Perhaps you should try some spelling variations:
wang yang » wang yan, wang yanling
weit kang » zeit kant
dong hua » wang hua, dong hoi, dong xu
kang kim » kanaga kim, tan kim, yong kim
tong hui » wang hui
dong bin » dong sin, dong di, dann bin
a weit » a west, a soweit
y a » y la

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yang) or (wang liang))) or (dong bin)) y a weit kang kim ((dong hua) OR (tong hui)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang liang))) OR (dong bin)) y a weit kang kim ((dong hua) OR (tong hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) or (wang liang))) or (dong bin)) y a weit kang kim ((dong hua) OR (tong hui)) ;*".
