Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
shang hai » shang kai, dang hai, chang ha
lang yan » wang yan, wang yang, zhang yan
chai tan » chai tam, chai onn
tan sang » tan yang, tang tang, tan hong
ka chai » ka chuan, kim chai
yan ka » yang ka, yuan kai
hong » long

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ka chai tan sang minh ((shang hai) OR (hong tan)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ka chai tan sang minh ((shang hai) OR (hong tan)) ;*.
