Perhaps you should try some spelling variations:
nhanh thanh » phan thanh, nhanh tinh
thien thanh » tien thanh, thi thanh, hien hanh
doan thien » hoan thien, doan thi, toan thiet
nhung cong » dung cong, thong cong, hang cong
hanh hanh » hanh han, xanh hanh, thanh thanh
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van 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 thien thanh - ((hanh hanh) OR (nhanh thanh)) va nhung cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan thien thanh - ((hanh hanh) OR (nhanh thanh)) va nhung cong dan ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doan thien thanh - ((hanh hanh) OR (nhanh thanh)) va nhung cong dan ((toan cau) or (toan ban))*.
