Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
phong hanh » phong thanh, phuong hanh, hong hanh
chau tinh » cuu tinh, ha tinh, cua tinh
hanh cong » thanh cong, hang cong, hanh dong
cong dung » cuong dung, cong dong, cong luong
va phan » van phan, va phat, va phap

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 ((chieu tinh) OR (chau tinh)) - khanh phong hanh cong dung va phan tu~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chau tinh)) - khanh phong hanh cong dung va phan tu*.
