Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang kang » yang yang, yang guang, yang liang
shang hai » dang hai, chang ha, hong hai
run gain » run pain
kang ya » kang ca, wang yan, kong yam
ya 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 kang ya run gain ((tan li) or (sang minh)) ((shang kai) OR (shang hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang kang ya run gain ((tan li) OR (sang minh)) ((shang kai) OR (shang hai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang kang ya run gain ((tan li) or (sang minh)) ((shang kai) OR (shang hai)) ;*".
