Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
nhan dinh » nhan sinh, phan dinh, nhan tinh
tong cong » trong cong, cong cong, dung cong
cong hach » cong sach, cong thanh, cong khanh
hach toan » thanh toan, manh toan
dinh cuu » dinh chi
cuu tong » cuu cong, cuu tinh, huu tung
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: "doi ((chieu tinh) OR (trieu tinh)) - nhan dinh cuu tong cong hach toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (trieu tinh)) - nhan dinh cuu tong cong hach toan cau*.
