Perhaps you should try some spelling variations:
trinh nhung » trinh phuong, trinh dung
tran trong » gian trong, quan trong, tran hong
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
anh quang » anh xquang, anh quan, nhanh quang
chi tach » chiu trach, chiet tach, chi thanh
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 tach - anh quang ((trinh nhung) OR (tran trong)) cong thanh toan cao~.
• Adding a wildcard symbol may retrieve word variants: doi chi tach - anh quang ((trinh nhung) or (tran trong)) cong thanh toan cao*.
