Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
truong cua » truong ca, truong quan, truong cao
thong cong » trong cong, tong cong, thong thong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » trung tuan, trung cap, dung cua
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, 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: theo ((hieu manh) OR (chieu tinh)) - thanh ((trung cua) OR (truong cua)) thong cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu tinh)) - thanh ((trung cua) OR (truong cua)) thong cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu tinh)) - thanh ((trung cua) OR (truong cua)) thong cong dan than cau*.
