Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thong cong » trong cong, tong cong, thong thong
thanh toan » thanh hoa, thanh san
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
ho chieu » theo chieu, hoc thieu, doi chieu

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