Perhaps you should try some spelling variations:
theo chu » theo chieu, cho chu, chao chu
chu tinh » chau tinh, chua tinh, cuu tinh
cong san » cong tac
tran cau » tran chau, toan cau, tra cau
mang he » bang he, mang ke, nang he
mang se » jang se, mang ke, lang set
ran cau » van cau, ban cau, can cau

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: theo chu tinh - nhanh ((mang he) OR (mang se)) trong cong san ((tran cau) OR (ran cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu tinh - nhanh ((mang he) or (mang se)) trong cong san ((tran cau) OR (ran cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chu tinh - nhanh ((mang he) or (mang se)) trong cong san ((tran cau) OR (ran cau))*.
