Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
hanh dung » thanh dung, hanh dong, manh dung
bang cong » dang cong, bang song, hang cong
anh dung » anh dong, anh huong, sach dung
cua bang » chua bang, cua ban, cua dang
cong tac » cong ty
toan tap » toan ban
toan cao » toan ban
ho lieu » so lieu, co lieu, ho kieu

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: ho lieu tinh - ((hanh dung) OR (anh dung)) cua bang cong tac ((toan tap) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - ((hanh dung) or (anh dung)) cua bang cong tac ((toan tap) or (toan cao))*.
