Perhaps you should try some spelling variations:

tieu xanh » tieu danh, chieu xanh, dieu hanh
thang van » tang van, thanh van, thong van
van dang » van dong, van dung, van nang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
nhan tai » hang tai, van tai, toan tai
han tap » han tai, toan tap, nhan tao

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 - nhanh thang van dang ((cong dan) OR (cong tan)) ((han tap) OR (nhan tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - nhanh thang van dang ((cong dan) or (cong tan)) ((han tap) OR (nhan tai))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - nhanh thang van dang ((cong dan) or (cong tan)) ((han tap) OR (nhan tai))*.
