Perhaps you should try some spelling variations:
hanh thang » nhanh thang, thanh thang, hanh trang
hieu lang » chieu sang, hieu quang, nhieu tang
manh toan » thanh toan, anh tuan, tinh toan
he trong » he thong, he trung, le trong
dan toan » van toan, dan than, xuan toan
ho hieu » ho chieu, hoi hieu, nho hieu
he dong » ha dong, de dong, he cong

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 hieu lang - hanh thang ((he dong) OR (he trong)) cong ((dan toan) OR (manh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: ho hieu lang - hanh thang ((he dong) or (he trong)) cong ((dan toan) or (manh toan)) cao*.
