Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
pei zwang » kein zwang, der zwang, dem zwang
zwang 3.2 » zwang 2.2
3.2 long » 3.2 land
tuan hua » yuan hui
yan guan » gan guan, yan yuan, yang guang
tan hua » wang hua, tan chia, tan puay
tuan vu » thanh vu
long du » long d, long do, long run

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: ((yang liang) OR (yan guan)) ((((tuan vu) OR (tuan hua))) OR (tan hua)) pei zwang 3.2 long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yan guan)) ((((tuan vu) OR (tuan hua))) or (tan hua)) pei zwang 3.2 long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yan guan)) ((((tuan vu) OR (tuan hua))) or (tan hua)) pei zwang 3.2 long du ;*.
