Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
hanh trinh » canh tranh, hanh chinh
trinh doan » trinh toan, thinh doan, trinh dan
doan nhung » doanh nhung, doan hung, doan phuong
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, than cap

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: "toc thieu tinh - hanh trinh doan nhung ((cong dan) OR (cong tan)) than cau~".
• Adding a wildcard symbol may retrieve word variants: toc thieu tinh - hanh trinh doan nhung ((cong dan) OR (cong tan)) than cau*.
