Perhaps you should try some spelling variations:
tran thanh » ban thanh, van thanh, quan thanh
nhung cong » dung cong, thong cong, hang cong
tran tuan » tran xuan, tran quang, tranh luan
chi xanh » chi anh, chi danh, chieu xanh
chi hanh » chi nhanh, chi thanh, thi hanh
cong van » cong vang, cong san, song van
van tan » van tuan, van ban, van tai
tan cau » toan cau, van cau, tan ca

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

• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi hanh)) - hanh ((tran tuan) OR (tran thanh)) nhung cong van tan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) or (chi hanh)) - hanh ((tran tuan) OR (tran thanh)) nhung cong van tan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) or (chi hanh)) - hanh ((tran tuan) OR (tran thanh)) nhung cong van tan cau*.
