Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh pham » thanh pho, thanh hai
thanh phan » thanh pho, thanh san, thanh toan
hoc thieu » toc thieu, hoc hien
dung cong » dung trong
cong san » cong tac
toan cao » toan ban
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu xanh - hanh ((thanh pham) OR (thanh phan)) dung cong san ((toan cao) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh ((thanh pham) OR (thanh phan)) dung cong san ((toan cao) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((thanh pham) OR (thanh phan)) dung cong san ((toan cao) or (toan tap))*".
