Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
chang hai » chang ha, shang hai, change has
yau yung » au yong, yap yun
yan yuan » yan guan, fang yuan, nan yan
yi chang » ii chang, ying chang, jin chang
yan yun » yang yun, yap yun, tang yun
yan kun » yan guan
yang yi » yang di, yang xi, yang jui
wang » wing, wan, 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 yan ((((yan yun) OR (yau yung))) OR (((yan kun) OR (yan yuan)))) gain yang yi chang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yan yun) or (yau yung))) or (((yan kun) OR (yan yuan)))) gain yang yi chang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yan yun) or (yau yung))) or (((yan kun) OR (yan yuan)))) gain yang yi chang hai ;*.
