Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
sang minh » kang minah, anh minh, song min
run gain » run pain
hong hai » shang hai, zhong tai, dang hai
ca run » can run, a run
tan li » tang li, tian li, gan li

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang guang) OR (yang liang)) ca run gain ((tan li) or (sang minh)) hong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang guang) OR (yang liang)) ca run gain ((tan li) OR (sang minh)) hong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang guang) OR (yang liang)) ca run gain ((tan li) or (sang minh)) hong hai ;*".
