Perhaps you should try some spelling variations:
tran thanh » ban thanh, van thanh, quan thanh
hanh trinh » canh tranh, hanh chinh
ghep nhung » nghiep nhung, hee nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
tan » than, tuan, tang

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: "tan tran thanh - hanh trinh ((ghep nhung) OR (thep khung)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: tan tran thanh - hanh trinh ((ghep nhung) OR (thep khung)) cong dan toan cau*.
