Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
hoc thieu » hoc hien
cap nhung » cam nhung, vap nhung, dap nhung
tran tuan » tran xuan, tran quang, tran thanh
cong tac » cong ty
tac tran » tan tran, tac trai, tac tren

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: ((hoc thieu) OR (toc thieu)) xanh - ((thanh trung) OR (thanh tung)) cap nhung cong tac tran tuan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (toc thieu)) xanh - ((thanh trung) OR (thanh tung)) cap nhung cong tac tran tuan~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (toc thieu)) xanh - ((thanh trung) OR (thanh tung)) cap nhung cong tac tran tuan*.
