Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
cua thong » cua thuong, cua khong, cua tong
cap chon » cap cho, tap chon, tap cho
chon van » chon va, thong van, phong van
cong dan » cong san, cong tan, huong dan
toan cao » toan ban
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: "cap chon van - hanh trinh cua thong cong dan ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: cap chon van - hanh trinh cua thong cong dan ((toan cao) OR (toan tap))*.
