Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
3.2 longer » 3.2 langere, 3 longer, 3.2 finger
tuan hua » tuan vu, yuan hui
wei yang » pei yang, wei wang, wei yang's
3.2 long » 3.2 land
tan hua » wang hua, tan chia, tan puay

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 liang) OR (yang guang)) ((tuan hua) OR (tan hua)) wei yang ((3.2 longer) OR (3.2 long)) a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (yang guang)) ((tuan hua) or (tan hua)) wei yang ((3.2 longer) OR (3.2 long)) a ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang guang)) ((tuan hua) or (tan hua)) wei yang ((3.2 longer) OR (3.2 long)) a ;*.
