Perhaps you should try some spelling variations:
cheng leong » chee leong, cheng ling
cheng tong » chung tong, chen rong, chen yong
cheng ming » cheng bing, cheng ling, chen ping
jeng dong » eng hong, zeng doug
qian yan » qian jun, qian yi
yan wang » yuan wang, yang yang, qian wang
wang di » yang di, wang d, wang li
sin » sign, sind, skin

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: qian yan wang di ((((cheng tong) OR (cheng leong))) OR (cheng ming)) jeng dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan wang di ((((cheng tong) or (cheng leong))) or (cheng ming)) jeng dong sin ;*.
