Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh mang » nhanh mang, hanh trang, nhanh lang
dung cong » dung trong
mang cua » manh cua, dung cua, ban cua
cua dung » cua dang, cua dong, qua dung
ban phan » van phan, ban than, ban nhan

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 ((hieu manh) OR (chieu sang)) - hanh mang cua dung cong ((ban phan) OR (ban phap)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sang)) - hanh mang cua dung cong ((ban phan) or (ban phap)) cau*.
