Perhaps you should try some spelling variations:
chen wang » chen yang, chen rong, chen ping
gan qian » gan guan, gan jiao, jun qian
qian yan » qian jun, qian yi
yang zhi » wang zhi, yan zhi, liang zhi
can see » can seem, can she, can seize
van en » van den, van een, van es
yan zi » yan zhi, yuan zi
ban zi » ban ji

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: gan qian yan ((van en) OR (can see)) chen wang ((yang zhi) OR (((yan zi) OR (ban zi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: gan qian yan ((van en) or (can see)) chen wang ((yang zhi) or (((yan zi) or (ban zi)))) ;*.
