Perhaps you should try some spelling variations:

chieu xanh » chieu sach, chieu sang, chieu tinh
nha chung » cua chung, nha hang
ho chieu » theo chieu, hoc thieu, doi chieu
cong ban » cong bang, cong tan, cong dan
cong san » cong tac
phap cac » phap cach, pha cac, phap ca
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: ho chieu xanh - thanh trong nha chung ((cong ban) OR (cong san)) ((phap cac) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trong nha chung ((cong ban) OR (cong san)) ((phap cac) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trong nha chung ((cong ban) OR (cong san)) ((phap cac) or (phan cac))*.
