Perhaps you should try some spelling variations:
dung phuong » dung thuong, bang phuong, dung chung
phuong doan » phuong loan, phuong hoang, huong dan
truong cua » truong ca, truong quan, truong cao
tieu xanh » tieu danh, chieu xanh, tien anh
trung cua » trung tuan, trung cap, dung cua
doan luan » doanh luan, dan luan, doan quan
luan cu » tuan cu, luan chi, quan cua

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: theo ((tieu xanh) OR (dieu hanh)) - thanh ((trung cua) OR (truong cua)) dung phuong doan luan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (dieu hanh)) - thanh ((trung cua) OR (truong cua)) dung phuong doan luan cu~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (dieu hanh)) - thanh ((trung cua) OR (truong cua)) dung phuong doan luan cu*.
