Perhaps you should try some spelling variations:
truong cong » trong cong, truong dong, truong long
nhanh long » nhanh dong, thanh long, nhanh song
nhanh lang » nhanh quang, nhanh thang, nhan dang
tieu tinh » trieu tinh, tieu trinh, lieu tinh
cong dan » cong san, cong tan, huong dan
than tap » toan tap, han tap, than cap
phan tap » phan lap, han tap, pha 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: theo tieu tinh - ((nhanh long) OR (nhanh lang)) cac truong cong dan ((than tap) OR (phan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu tinh - ((nhanh long) or (nhanh lang)) cac truong cong dan ((than tap) OR (phan tap))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu tinh - ((nhanh long) or (nhanh lang)) cac truong cong dan ((than tap) OR (phan tap))*.
