Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
trung tuan » trung thanh, trung tam, truong thanh
hoc thieu » toc thieu, hoc hien
tran tuan » tran xuan, tran quang, tran thanh
trong dan » trong dang, trong san, trong tan
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tap

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: hoc thieu xanh - thanh ((trung tuan) OR (tran tuan)) han ((cong dan) OR (trong dan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh ((trung tuan) OR (tran tuan)) han ((cong dan) or (trong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((trung tuan) OR (tran tuan)) han ((cong dan) or (trong dan)) toan cau*.
