Perhaps you should try some spelling variations:
fang sudan » fang sidun, fang yuan, fund sudan
sudan chen » sudan ch
long chain » long chemin, long grain, long han
chen yue » chen yu, chen yun, chen yulu
yue gain » you gain, run gain, yue man
yang yun » yang jun, tang yun, yang yang
yang yue » wang yue, yang jui, wong yue
yang yi » yang xi, yang jui

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: fang sudan chen yue gain ((((((yang yun) OR (yang yue))) OR (yang yi))) OR (yang di)) long chain ;~.
• Adding a wildcard symbol may retrieve word variants: fang sudan chen yue gain ((((((yang yun) or (yang yue))) or (yang yi))) or (yang di)) long chain ;*.
