Perhaps you should try some spelling variations:
wang luhang » wang liang, wang lihong, wang susheng
wang yuhan » wang yan, wang yidan, fang yuan
ahsan syed » khan syed
chan tung » chan eng, chan fong, chan kang
tung chen » yung chen, tung chung, kang chen
chen zhi » chen zhe, chen zhen, chen chih
can see » can seem, can she, can seize

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 luhang) OR (wang yuhan)) kang ((can see) OR (ahsan syed)) chan tung chen zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang luhang) OR (wang yuhan)) kang ((can see) or (ahsan syed)) chan tung chen zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang luhang) OR (wang yuhan)) kang ((can see) or (ahsan syed)) chan tung chen zhi ;*.
