phan shen » han shen, than she
khan sher » han shen, khan syed, than she
yang dan » yang dean, yang fan, wang dan
wang yue » wong yue, wang hua, wang yan

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 yang dan ((phan shen) OR (khan sher)) ((chang kwok) OR (chang deok)) wang yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang dan ((phan shen) or (khan sher)) ((chang kwok) OR (chang deok)) wang yue ;*".
