Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thien tinh » khien tinh, thien minh, tien tinh
hoc thien » hoc hien, hoc thieu, hoc thiet
manh hung » anh huong
cua nhung » va nhung
hung cua » huong cua, chung cua, khung cua
cong tan » cong tac, cong san, cong thanh
toan tai » toan tap, doanh tai, von tai
toan cao » toan tap
toan ban » van ban

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 tinh - manh hung cua nhung cong tan ((((toan tai) OR (toan cao))) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc thien tinh - manh hung cua nhung cong tan ((((toan tai) or (toan cao))) or (toan ban))*.
