Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
hanh trang » thanh trung, canh tranh, hanh trinh
van nhung » van nhuong, van hung, van phung
theo chu » theo chieu, cho chu, chao chu
chu manh » ho manh, chu han, chu van
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: theo chu manh - ((nhanh lang) OR (hanh trang)) ((van nhung) OR (va nhung)) cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu manh - ((nhanh lang) or (hanh trang)) ((van nhung) OR (va nhung)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu manh - ((nhanh lang) or (hanh trang)) ((van nhung) OR (va nhung)) cong dan toan cau*.
