Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
hoc thieu » toc thieu
pho dong » pho uong, pho thong, phan dong
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan tap » toan ban
co dong » o dong, cong dong, lao dong

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 (hoc hien)) xanh - thanh dung ((co dong) or (pho dong)) cong tac toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - thanh dung ((co dong) OR (pho dong)) cong tac toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - thanh dung ((co dong) or (pho dong)) cong tac toan tap".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - thanh dung ((co dong) or (pho dong)) cong tac toan tap*.
