Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
trung cua » truong cua, trung tuan, trung cap
dung cong » dung trong
tung cua » tuong cua, dung cua, tang cua
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 ((chieu tinh) OR (chau tinh)) - thanh ((tung cua) OR (trung cua)) dung cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chau tinh)) - thanh ((tung cua) OR (trung cua)) dung cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chau tinh)) - thanh ((tung cua) OR (trung cua)) dung cong dan than cao*.
