Perhaps you should try some spelling variations:
wang liang » wang yang
yang guang » yang yang, yan guan, yang liang
4.3 longer » 4.3 long, 4.3 lower
longer do » longer _, longer a, long do
tan chia » tuan china, than china, can china
pei yang » hui yang, pei yun, yi yang
wei yang » wei wang, wei yang's, wei shang

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)) tan chia ((pei yang) OR (wei yang)) 4.3 longer do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (yang guang)) tan chia ((pei yang) OR (wei yang)) 4.3 longer do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang guang)) tan chia ((pei yang) OR (wei yang)) 4.3 longer do ;*.
