Perhaps you should try some spelling variations:
tieu tinh » trieu tinh, tieu trinh, lieu tinh
hanh mang » nhanh mang, hanh trang, nhanh lang
cua trung » cua truong, xuan trung, ba trung
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu tinh - hanh mang ((cua trung) OR (cua nhung)) cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu tinh - hanh mang ((cua trung) OR (cua nhung)) cong dan than cap*.
