Perhaps you should try some spelling variations:
dung phuong » dung thuong, bang phuong, dung chung
phuong van » phung van, phong van, phuong lan
hoc thieu » toc thieu
thanh tri » thanh tra, thanh tai, chinh tri
van toan » van tuan, van tan, van thanh
toan tap » toan ban
tri ung » trinh ung, tri cong

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - thanh tri ung dung phuong van toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - thanh tri ung dung phuong van toan tap*.
