Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
hoc chieu » hoc thieu, ho chieu, hoc thiet
hoc dieu » hoc thieu
cong dan » cong san, cong tan, huong dan
tung va » trung va, tuong va, dung va
dan van » dang van, doan van, dao 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) OR (hoc dieu))) or (hoc hien)) xanh - thanh tung va nhung cong dan van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hoc chieu) OR (hoc dieu))) OR (hoc hien)) xanh - thanh tung va nhung cong dan van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hoc chieu) OR (hoc dieu))) or (hoc hien)) xanh - thanh tung va nhung cong dan van ban*".
