Perhaps you should try some spelling variations:
trinh quan » trinh luat, trinh han
dong thanh » truong thanh
thanh toan » thanh hoa, thanh san, tinh toan
hien xanh » hien nhanh, chieu xanh, hien khanh
hien hanh » dieu hanh
vung dong » cong dong
toan ban » van ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien xanh) OR (hien hanh)) - hanh ((trinh quan) or (tinh quang)) vung dong thanh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien hanh)) - hanh ((trinh quan) OR (tinh quang)) vung dong thanh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien hanh)) - hanh ((trinh quan) or (tinh quang)) vung dong thanh toan ban".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (hien hanh)) - hanh ((trinh quan) or (tinh quang)) vung dong thanh toan ban*.
