Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hien xanh » hien hanh, hien nhanh, chieu xanh
hanh tran » hanh trang, hanh tram, thanh trang
xuan dung » tuan dung, xuan hung, quang dung
dung cong » dung trong
cong tac » cong ty
toan cao » toan ban, toan tap

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

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