Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
hoc chieu » hoc thieu, ho chieu, hoc hien
van dung » van dong, xay dung, tin dung
ap dung » xay dung
dan van » dang van, doan van, tan van
dao van » do van, dang van

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu xanh - thanh tung ((ap dung) or (van dung)) cong ((dan van) OR (dao van)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - thanh tung ((ap dung) OR (van dung)) cong ((dan van) OR (dao van)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - thanh tung ((ap dung) or (van dung)) cong ((dan van) OR (dao van)) ban*".
