Perhaps you should try some spelling variations:
thanh huong » thanh cong, anh huong, thanh tung
thanh hung » thanh tung, thanh trung, thanh cong
hoc thieu » hoc hien
dung cong » dung trong
van dung » van dong, xay dung, tin dung
cong tac » cong ty
tac van » tac vang, cac van, tac va

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) or (toc thieu)) manh - ((thanh huong) OR (thanh hung)) van dung cong tac van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) manh - ((thanh huong) OR (thanh hung)) van dung cong tac van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (toc thieu)) manh - ((thanh huong) OR (thanh hung)) van dung cong tac van ban*".
