Perhaps you should try some spelling variations:
cua truong » cua trung, xuan truong, cac truong
chieu tinh » lieu tinh, chau tinh, kieu tinh
canh manh » lanh manh, canh tranh, cach mang
cua trong » cua trung, qua trong, ca trong
cong dan » cong san, cong tan, huong dan
dan chat » van chat, dan chan, ban chat
chat cao » chat co, chat cho, chat bao

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 ((chieu tinh) OR (trieu tinh)) - canh manh ((cua trong) OR (cua truong)) cong dan chat cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) or (trieu tinh)) - canh manh ((cua trong) OR (cua truong)) cong dan chat cao~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) or (trieu tinh)) - canh manh ((cua trong) OR (cua truong)) cong dan chat cao*.
