Perhaps you should try some spelling variations:
thien hach » thien thanh, hien hanh
nhanh lang » nhanh quang, nhanh thang, nhan dang
hoc thien » hoc hien, hoc thieu, hoc thiet
cua nhung » va nhung
lang cua » mang cua, hang cua, long cua
cong tac » cong ty
can cau » van cau, ban cau, ca 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: hoc thien hach - nhanh lang cua nhung ((cong san) OR (cong tac)) can cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thien hach - nhanh lang cua nhung ((cong san) or (cong tac)) can cau*.
