Perhaps you should try some spelling variations:
phuong thanh » phong thanh, truong thanh, phuong thao
dung phuong » dung thuong, bang phuong, dung chung
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh toan » thanh hoa, thanh san, tinh toan
doi chieu » doc hieu, doi chi, ho chieu
tang vatn » tang van, dang van, tan van
tang vat » tang van, dang vat, bang vat
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 chieu xanh - hanh ((tang vat) OR (tang vatn)) dung phuong thanh toan ban~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh ((tang vat) or (tang vatn)) dung phuong thanh toan ban*.
