Perhaps you should try some spelling variations:
cheng leong » chee leong, cheng ling
cheng tong » chung tong, chen rong, chen yong
chen ping » chen rong, chen yang, chen wang
jeng dong » eng hong, zeng doug
qian yan » qian jun, qian yi
yan wang » yuan wang, yang yang, qian wang
wang lei » wang wei, wang fei, 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 lei ((((cheng tong) OR (cheng leong))) OR (chen ping)) jeng dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan wang lei ((((cheng tong) or (cheng leong))) or (chen ping)) jeng dong sin ;*.
