Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
dung cong » dung trong
cong tac » cong ty
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac
ho lieu » so lieu, co lieu, ho kieu

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: ho lieu tinh - thanh ((trung cua) OR (trung cap)) dung cong tac ((than cau) OR (than cap))~.
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - thanh ((trung cua) or (trung cap)) dung cong tac ((than cau) or (than cap))*.
