Perhaps you should try some spelling variations:
meng yuan » meng hsuan, fang yuan, feng juan
gain yang » dan yang, daun yang, tan yang
shang hai » shang kai, dang hai, chang ha
yan guan » gan guan, yang guang, yihan guan
yan yuan » fang yuan, nan yan, yan clan
di shang » wei shang, xia shang, _ shang
wang » wing, lang

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 OR wan) yan ((((yan yuan) OR (yan guan))) OR (meng yuan)) gain yang di shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan ((((yan yuan) OR (yan guan))) or (meng yuan)) gain yang di shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan ((((yan yuan) OR (yan guan))) or (meng yuan)) gain yang di shang hai ;*.
