Perhaps you should try some spelling variations:
chieu sang » chieu xanh, hieu lang, nhieu tang
chieu sach » chinh sach, chiet tach, chieu xanh
nhung cong » dung cong, thong cong, hang cong
trinh han » trinh quan
san quang » van quang, dan quang, san quan
quang cao » nang cao, quang nam
trinh he » trinh hoa, trinh thi, trinh ky
cong san » cong tac

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 sang) OR (chieu sach)) - canh ((trinh he) OR (trinh han)) nhung cong san quang cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chieu sach)) - canh ((trinh he) OR (trinh han)) nhung cong san quang cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chieu sach)) - canh ((trinh he) OR (trinh han)) nhung cong san quang cao*.
