Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
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
dan than » ban than, van than, dan toan
dan chan » dan gian, dan ca, van chat

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 ((chieu xanh) OR (chieu sang)) - hanh mang cua dung cong ((dan than) OR (dan chan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sang)) - hanh mang cua dung cong ((dan than) OR (dan chan)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sang)) - hanh mang cua dung cong ((dan than) OR (dan chan)) cao*.
