Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trong tinh » truong tinh, trong kinh, trong sinh
ho chieu » theo chieu, hoc thieu, doi chieu
dang van » hoang van, hang va
cang vat » dang vat, bang vat, hang va
toan ban » van ban
bang va » hang va, ban va, trang va

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 - canh ((((dang van) OR (bang va))) OR (cang vat)) dung trong tinh toan ban~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh ((((dang van) or (bang va))) or (cang vat)) dung trong tinh toan ban*.
