Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhung cong » dung cong, thong cong, hang cong
trung va » truong va, trang va, trung tam
trung ha » trung hoc, trung tam, trung cap
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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 ((chieu xanh) OR (chieu tinh)) - thanh ((trung va) OR (trung ha)) nhung cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - thanh ((trung va) OR (trung ha)) nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - thanh ((trung va) OR (trung ha)) nhung cong tan toan tap*.
