Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
trang cua » tang cua, trung cua, thang cua
tranh cua » doanh cua, manh cua
ho trieu » mot trieu, 25 trieu, 30 trieu
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - hanh ((trang cua) OR (tranh cua)) thong cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - hanh ((trang cua) OR (tranh cua)) thong cong tac toan cau*.
