Perhaps you should try some spelling variations:
trinh luan » trinh luat, trinh quan, trinh han
chinh luan » chinh ngan, binh luan
chau tinh » cuu tinh, ha tinh, cua tinh
dong cong » duong cong, dung cong, dang cong
cong tac » cong ty
than cau » toan cau, phan cau, than cap
phan cac » nhan cach, phan dau, phan lap
ho chau » ha chau, ho chu, o chau

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: ho chau tinh - hanh ((chinh luan) OR (trinh luan)) dong cong tac ((than cau) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - hanh ((chinh luan) OR (trinh luan)) dong cong tac ((than cau) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - hanh ((chinh luan) OR (trinh luan)) dong cong tac ((than cau) or (phan cac))*.
