Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, truong thanh
duong manh » duong van
tran tuan » tran xuan, tran quang, tran thanh
ho chieu » theo chieu, hoc thieu, doi chieu
luong va » dung va
toan cau » toan cao, toan ban, toan tap

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 ((trung tuan) OR (tran tuan)) nhung ((duong manh) OR (luong va)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((trung tuan) OR (tran tuan)) nhung ((duong manh) or (luong va)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((trung tuan) OR (tran tuan)) nhung ((duong manh) or (luong va)) toan cau*.
