Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cua » truong ca, truong quan, truong cao
cong doanh » cong danh, cong doan, dong doanh
trung cua » trung tuan, trung cap, dung cua
ban cong » bang cong, van cong, phan cong
doanh va » doan va, doanh tai, doanh cua
va ban » van ban, va bai, va bao

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: hoc ((thieu xanh) OR (chieu xanh)) - thanh ((trung cua) OR (truong cua)) ban cong doanh va ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - thanh ((trung cua) or (truong cua)) ban cong doanh va ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - thanh ((trung cua) or (truong cua)) ban cong doanh va ban*.
