Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
tranh cua » manh cua
doanh cua » doanh luan
thanh lap » thanh san, phan lap, thanh hai
thanh cac » hanh cac, thanh bac, thanh ca
ho chieu » theo chieu, hoc thieu, doi chieu
dan cong » dang cong, van cong, dan dong
cong tac » cong ty

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 chieu tinh - hanh ((tranh cua) OR (doanh cua)) dan cong tac ((thanh lap) OR (thanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh ((tranh cua) OR (doanh cua)) dan cong tac ((thanh lap) or (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh ((tranh cua) OR (doanh cua)) dan cong tac ((thanh lap) or (thanh cac))*.
