Perhaps you should try some spelling variations:
tinh thong » tinh thuong, trinh thong, tinh khong
quang toan » quang tuan, quang tran, quang doan
trien soat » trien hoat, trien san, thien hoat
kiem soat » kiem toan
toan va » doan va, tran van, toan ban
va kiem » van kien
quan va » quan vi, quan ha, quan ve
luan va » luan van, luat va

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: (( tinh quang toan va kiem soat ) OR ( tinh thong ((quan va) OR (luan va)) trien soat ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh quang toan va kiem soat ) or ( tinh thong ((quan va) OR (luan va)) trien soat ))~".
• Adding a wildcard symbol may retrieve word variants: (( tinh quang toan va kiem soat ) or ( tinh thong ((quan va) OR (luan va)) trien soat ))*.
