Perhaps you should try some spelling variations:
yang qiang » yang liang, wang liang, yang yang
wang yang » wang yan, wang liang, wang yanling
jeng dong » eng hong, zeng doug
als last » als gast, his last, its last
li last » i last, die last, his last
a last » _ last, a las
thing » things, think, thin
sin » sign, sind, skin

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