Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
chau tinh » cuu tinh, ha tinh, cua tinh
lieu tinh » trieu tinh, diep tinh, bien tinh
tran tuan » tran xuan, tran quang, tran thanh
tuan tong » toan tong, thuan trong, toan thong
chinh can » chinh ca, chinh ban, chinh cau
cong dan » cong san, cong tan, cong dong

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: doi ((chau tinh) OR (lieu tinh)) - thanh tran tuan tong ((cong dan) OR (huong dan)) chinh can~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chau tinh) or (lieu tinh)) - thanh tran tuan tong ((cong dan) OR (huong dan)) chinh can~".
• Adding a wildcard symbol may retrieve word variants: doi ((chau tinh) or (lieu tinh)) - thanh tran tuan tong ((cong dan) OR (huong dan)) chinh can*.
