Perhaps you should try some spelling variations:
tieu tinh » trieu tinh, tieu trinh, lieu tinh
dung cong » dung trong
hanh ban » thanh ban, hang ban, hanh san
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tai
toan cao » toan ban
toan tap » toan ban
ban cua » ban quan

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 - hanh ban cua dung cong dan ((toan cau) OR (((toan cao) OR (toan tap))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu tinh - hanh ban cua dung cong dan ((toan cau) or (((toan cao) OR (toan tap))))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu tinh - hanh ban cua dung cong dan ((toan cau) or (((toan cao) OR (toan tap))))*.
