Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
anh nang » ganh nang, anh bang, anh dang
nang ung » dang ung, nang luong, nang song
cong dan » cong tan, cong dong, cong tac
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac

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 - anh nang ung dung ((((cong dan) OR (cong san))) or (huong dan)) than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - anh nang ung dung ((((cong dan) OR (cong san))) OR (huong dan)) than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - anh nang ung dung ((((cong dan) OR (cong san))) or (huong dan)) than cap*".
