Perhaps you should try some spelling variations:
thieu tinh » chieu tinh, thien tinh, lieu tinh
hanh trung » thanh trung, hanh trang, manh trung
trung tham » trung tam, trung thanh, trung thang
tham hang » pham hang, thai hang, tham lang
cong dan » cong san, cong tan, cong dong
than man » than ma, thanh san, tran manh

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu tinh) OR (trieu tinh)) - hanh trung tham hang ((cong dan) or (huong dan)) than man~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu tinh) OR (trieu tinh)) - hanh trung tham hang ((cong dan) OR (huong dan)) than man.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu tinh) OR (trieu tinh)) - hanh trung tham hang ((cong dan) or (huong dan)) than man".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu tinh) OR (trieu tinh)) - hanh trung tham hang ((cong dan) or (huong dan)) than man*.
