Perhaps you should try some spelling variations:
cang thang » cong thanh, dang thanh
phap sinh » phau sinh, phap tinh
phai sinh » phau sinh, thai binh, pham minh
thang cua » thong cua, hang cua, than cua
bang cong » dang cong, bang song, hang cong
cua bang » chua bang, cua ban, cua dang
cong san » cong tac
toan tai » toan tap, doanh tai, toan ban
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: thi ((phap sinh) OR (phai sinh)) - cang thang cua bang cong san ((toan tai) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thi ((phap sinh) OR (phai sinh)) - cang thang cua bang cong san ((toan tai) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: thi ((phap sinh) OR (phai sinh)) - cang thang cua bang cong san ((toan tai) or (toan cao))*.
