Perhaps you should try some spelling variations:
yang qiang » wang liang, yang yang, gong qiang
yang liang » wang liang, yan liang, yang yang
last think » last thing, last things
think jeng » think long
jeng dong » eng hong, zeng doug
li last » i last, als last, die last
sin » sign, sind, skin

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 ((yang qiang) OR (yang liang)) li last think jeng dong sin ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang qiang) OR (yang liang)) li last think jeng dong sin ;*.
