Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
tran cuong » tan cuong, tran cong, tran tuong
cuong dung » tuong duong, ung dung, thong dung
trong bang » trong ban, trong dang, trong tang
bang thanh » ban thanh, dang thanh, tang thanh
thanh tap » thanh lap, thanh tai, thanh tay
hieu cua » hieu qua, dieu cua, bieu cua
hieu ca » hieu cac, hieu va, hieu xa

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: doc ((hieu ca) OR (hieu cua)) - thanh tran cuong dung trong bang thanh tap~.
• Adding a wildcard symbol may retrieve word variants: doc ((hieu ca) or (hieu cua)) - thanh tran cuong dung trong bang thanh tap*.
