Perhaps you should try some spelling variations:
phai nhuong » phan thuong, pham thuong, pham chuong
nhuong cong » nhung cong, luong cong, duong cong
chieu sang » chieu sach, chieu xanh, hieu lang
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trung » thanh trung, hanh trang, manh trung
trung phai » trung phan, trung hai, trung phat
cong dan » cong san, cong tan, huong dan
than cau » phan cau, than cap, thanh chau
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: hoc ((chieu sang) OR (chieu tinh)) - hanh trung phai nhuong cong dan ((than cau) OR (toan cau))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) or (chieu tinh)) - hanh trung phai nhuong cong dan ((than cau) or (toan cau))*.
