Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
siew pei » siew hai, chew pei, siew ee
pei yang » wei yang, hui yang, pei yun
6.2 long » 3.2 long, 3.1 long
3 long » a long, 3.2 long, 3.1 long
tham » than, them, cham

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) OR (yang guang)) tham siew pei yang ((3 long) OR (6.2 long)) do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) OR (yang guang)) tham siew pei yang ((3 long) OR (6.2 long)) do ;*.
