Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tranh cua » doanh cua
chao chu » cho chu, cua chu, chao xu
manh cua » doanh cua, ban cua
cong tac » cong ty
tac than » tac thanh, tam than, tac nhan
than man » than ma, thanh san, tran manh
cao cho » cap cho, cao chat

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: ((chao chu) OR (cao cho)) xanh - hanh ((tranh cua) OR (manh cua)) nhung cong tac than man~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chao chu) OR (cao cho)) xanh - hanh ((tranh cua) or (manh cua)) nhung cong tac than man~".
• Adding a wildcard symbol may retrieve word variants: ((chao chu) OR (cao cho)) xanh - hanh ((tranh cua) or (manh cua)) nhung cong tac than man*.
