Perhaps you should try some spelling variations:
thanh trung » thanh tung
hanh trang » canh tranh, hanh trinh, minh trang
qua trong » quan trong, qua trinh, qua song
ho nhieu » hop nhieu, he nhieu, hoc thieu
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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 nhieu) OR (ho chieu)) tang - ((hanh trang) OR (thanh trung)) qua trong cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho nhieu) OR (ho chieu)) tang - ((hanh trang) or (thanh trung)) qua trong cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho nhieu) OR (ho chieu)) tang - ((hanh trang) or (thanh trung)) qua trong cong tan toan tap*.
