Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, nhung don
hanh manh » hanh mang, lanh manh, hoang manh
hang cong » dang cong, hang nong, bang cong
thanh cac » hanh cac, thanh bac, thanh ca
khi hanh » thi hanh, chi hanh, chi nhanh
manh cua » doanh cua, ban cua
than cap » khan cap, thanh lap, than cua

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: doi khi hanh - hanh manh cua ((nhung cong) OR (hang cong)) sang ((than cap) OR (thanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi khi hanh - hanh manh cua ((nhung cong) or (hang cong)) sang ((than cap) OR (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: doi khi hanh - hanh manh cua ((nhung cong) or (hang cong)) sang ((than cap) OR (thanh cac))*.
