Perhaps you should try some spelling variations:
chung kang » chan kang, chung kay, chung tong
kang chung » kung chung, kang young, dang hung
fang yuan » wang yuhan, wang yan, meng yuan
khan sher » han shen, than she
khan syed » shah syed
chung zhi » chung chi, chen zhi, chung h
yuan kai » yuan kang, yuan fei, tan kai

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: fang yuan kai ((((khan sher) OR (khan syed))) OR (ahsan syed)) chung kang chung zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fang yuan kai ((((khan sher) OR (khan syed))) or (ahsan syed)) chung kang chung zhi ;~".
• Adding a wildcard symbol may retrieve word variants: fang yuan kai ((((khan sher) OR (khan syed))) or (ahsan syed)) chung kang chung zhi ;*.
