Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
tonga eiu » kong eiu
yan guan » gan guan, yan yuan, yihan guan
ming koo » ming kong, myung koo, ting kok
wai yan » wang yan, wei yang
dong di » dong sin
ya yuan » yan yuan
kang » lang, wang, kong

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wai yan) or (dong di)) ((ya yuan) or (((yan guan) OR (yang guang)))) ming koo kang tonga eiu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wai yan) OR (dong di)) ((ya yuan) OR (((yan guan) OR (yang guang)))) ming koo kang tonga eiu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (dong di)) ((ya yuan) or (((yan guan) OR (yang guang)))) ming koo kang tonga eiu ;*".
