Perhaps you should try some spelling variations:
canh trinh » canh tranh, hanh trinh, canh tinh
chau tinh » ha tinh, cua tinh, cac tinh
vat nhung » va nhung, vai nhung, ve nhung
vap nhung » va nhung, ve nhung, voi nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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: ho ((chau tinh) OR (cuu tinh)) - canh trinh ((vat nhung) OR (vap nhung)) cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (cuu tinh)) - canh trinh ((vat nhung) OR (vap nhung)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) or (cuu tinh)) - canh trinh ((vat nhung) OR (vap nhung)) cong dan toan cau*.
