Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thep chiu » theo chieu, thap chieu, theo chu
lanh manh » lanh tranh, lan anh, van manh
anh danh » anh anh, anh dang, anh dinh
van cong » van dong, van phong, phan cong
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
cua van » cua ban, cua vat, cua dan

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: thep chiu trach - ((lanh manh) OR (anh danh)) cua van cong thanh ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: thep chiu trach - ((lanh manh) or (anh danh)) cua van cong thanh ((toan cau) or (toan ban))*.
