Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trinh quan » tinh quang, trinh luat, trinh han
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
trinh van » trinh han, trinh toan, dinh van
cong dan » cong san, cong tan, huong dan
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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: doi chieu xanh - canh ((trinh van) OR (trinh quan)) nhung cong dan ((phan cau) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - canh ((trinh van) or (trinh quan)) nhung cong dan ((phan cau) OR (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - canh ((trinh van) or (trinh quan)) nhung cong dan ((phan cau) OR (phan cac))*.
