Perhaps you should try some spelling variations:
thanh tung » thanh cong
tuan nhung » tuan hung, thuat nhung, tranh nhung
quan nhung » qua nhung, cua nhung, luan chung
chi hanh » chi nhanh, chi thanh, thi hanh
cong dan » cong san, cong tan, huong dan
than cau » phan cau, than cap, thanh chau
toan cau » toan cao, toan ban, toan tap
doi chi » doi khi

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 hanh - thanh tung ((tuan nhung) OR (quan nhung)) cong dan ((than cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi hanh - thanh tung ((tuan nhung) OR (quan nhung)) cong dan ((than cau) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chi hanh - thanh tung ((tuan nhung) OR (quan nhung)) cong dan ((than cau) or (toan cau))*.
