Perhaps you should try some spelling variations:
tien thanh » tien thinh, tran thanh, den thanh
nhung cong » dung cong, thong cong, hang cong
doan tien » doan thien, doanh tien, toan tien
tranh he » tranh ha, tinh he, trang ha
trinh he » trinh han, trinh hoa, trinh thi
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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: doan tien thanh - canh ((tranh he) OR (trinh he)) nhung cong dan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tien thanh - canh ((tranh he) or (trinh he)) nhung cong dan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: doan tien thanh - canh ((tranh he) or (trinh he)) nhung cong dan ((toan cau) OR (toan tap))*.
