Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
doan tien » doan thien, doanh tien, toan tien
trinh he » trinh han, trinh hoa, trinh thi
dan toan » van toan, dan than, manh toan
toan tap » toan ban

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: "doan tien thinh - hanh trinh he ((nhung cong) OR (thong cong)) dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: doan tien thinh - hanh trinh he ((nhung cong) OR (thong cong)) dan toan tap*.
