Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
dang cong » dung cong
cho lieu » cho dieu, co lieu, ho lieu
hanh han » hanh nhan, hanh phan, hanh san
cua dang » cua cong, cua ban
cong san » cong tac
than cap » thanh lap, thanh cac, than va
than cua » nhan cua, thai cua, ban cua
khan cap » khan ap, khoan cam, phan cac
han cua » hang cua, nhan cua, hanh 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: cho lieu tinh - hanh han cua dang cong san ((((than cap) OR (than cua))) OR (khan cap))~.
• Adding a wildcard symbol may retrieve word variants: cho lieu tinh - hanh han cua dang cong san ((((than cap) or (than cua))) or (khan cap))*.
