Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu
cua nhung » va nhung
cong cua » cong cu, dong cua, huong cua
cong san » cong tac
san than » sang than, san thanh, ban than
than cao » toan cao, thai cao, than cap
doi chi » doi khi

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 hien) OR (hoc thieu))) OR (doi chi)) xanh - thanh cong cua nhung cong san than cao~.
• Adding a wildcard symbol may retrieve word variants: ((((hoc hien) or (hoc thieu))) or (doi chi)) xanh - thanh cong cua nhung cong san than cao*.
