Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
trung ha » trung hoc, trung cap
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh 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: hoc thieu xanh - thanh ((trung tam) OR (trung ha)) nhung cong dan toan tap~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((trung tam) or (trung ha)) nhung cong dan toan tap*.
