Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
trung tuan » trung thanh, trung tam, tran tuan
lang phong » bang phuong, luong phong, trang phong
hoc thieu » toc thieu, hoc hien
trung cap » truong cao, trung tam
lang phan » nang phan, lang thang, lang thanh

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