Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
doc hieu » toc thieu, hoc thieu, hoc hien
cong cua » cong cu, dong cua, huong cua
san than » sang than, san thanh, van than
ban than » ban thanh, van thanh, ban hang
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: ((doc hieu) OR (doi chi)) xanh - thanh cong cua nhung cong ((san than) OR (ban than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (doi chi)) xanh - thanh cong cua nhung cong ((san than) OR (ban than)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (doi chi)) xanh - thanh cong cua nhung cong ((san than) OR (ban than)) cao*.
