Perhaps you should try some spelling variations:
phuong luong » thuong luong, phuong duong, chuong duong
phuong dung » thong dung, cuong dung, phuong hoang
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tran » thanh trang, thanh toan, thanh tra
ho chieu » theo chieu, hoc thieu, doi chieu
tran van » luan van
than cap » khan cap, thanh lap, thanh cac
khan ap » khan cap, han ap, khan dam

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: ho chieu xanh - thanh tran van ((phuong luong) OR (phuong dung)) dao ((khan ap) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh tran van ((phuong luong) OR (phuong dung)) dao ((khan ap) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh tran van ((phuong luong) OR (phuong dung)) dao ((khan ap) or (than cap))*.
