Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
thong cong » trong cong, tong cong, thong thong
cong doan » cong dan, cong hoan, dong doanh
ho chieu » theo chieu, hoc thieu, doi chieu
phan cau » phan cac, phan tu, phan lap
phan dau » phan tu, hang dau

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 ((truong cua) OR (truong cao)) thong cong doan ((phan cau) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((truong cua) or (truong cao)) thong cong doan ((phan cau) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((truong cua) or (truong cao)) thong cong doan ((phan cau) OR (phan dau))*.
