Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
dang haji » dang hai, dato haji
wing yan » wang yan, wing ian, wing tan
tang yun » yang yun, chang yun, fang yuan
dan yang » daun yang, tan yang, wang yang
yan kun » yan guan, yan yuan
xi dang » xi kang, xi zhang

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