Perhaps you should try some spelling variations:
truong tinh » truong kinh, truong minh, truong dinh
dung truong » duong truong, dung trong, dung trung
lieu tinh » trieu tinh, diep tinh, bien tinh
doi lieu » duoc lieu, doi chieu, du lieu
tang vat » dang vat, bang vat, cang vat
tang van » dang van, hoang van, trong van
toan ban » van ban

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: doi lieu tinh - canh ((tang vat) OR (tang van)) dung truong tinh toan ban~.
• Adding a wildcard symbol may retrieve word variants: doi lieu tinh - canh ((tang vat) or (tang van)) dung truong tinh toan ban*.
