Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
gan guan » yan guan, quan guan, fan guon
yan qian » yan liang, jun qian, yan clan
hua ren » hua chen
rong su » rong yu, cong sun, jeong su
wang » wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wing) ((((yang guang) OR (yang liang))) or (gan guan)) hua ren yan qian rong su ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((((yang guang) OR (yang liang))) OR (gan guan)) hua ren yan qian rong su ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((((yang guang) OR (yang liang))) or (gan guan)) hua ren yan qian rong su ;*".
