Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
doi trieu » dong trieu, doi chieu, doi trinh
trinh cua » trinh luat, trinh quan, trinh luan
tinh cua » sinh cua, tinh chat, tranh cua
cong san » cong tac
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi trieu tinh - hanh ((trinh cua) OR (tinh cua)) nhung cong san than cap~".
• Adding a wildcard symbol may retrieve word variants: doi trieu tinh - hanh ((trinh cua) OR (tinh cua)) nhung cong san than cap*.
