Perhaps you should try some spelling variations:
trinh cua » trinh luat, trinh quan, trinh luan
cap chon » cap cho, tap chon, tap cho
chon van » chon va, thong van, phong van
tinh cua » sinh cua, tinh chat, tranh cua
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
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: cap chon van - hanh ((trinh cua) OR (tinh cua)) thong ((cong dan) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cap chon van - hanh ((trinh cua) or (tinh cua)) thong ((cong dan) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: cap chon van - hanh ((trinh cua) or (tinh cua)) thong ((cong dan) OR (cong san)) toan cao*.
