Perhaps you should try some spelling variations:
tinh dung » trinh dung, tin dung, tinh huong
kiem soat » kiem toan
hien soat » thien hoat, bien soan, hien luat
dung san » dong san, dung sai, dung luan
tuan van » luan van, tan van, quan van
tran van » luan van
va kiem » van kien
san va » san van, ban va, dan va

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh dung san va kiem soat ) or ( tinh quang ((tuan van) OR (tran van)) hien soat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh dung san va kiem soat ) OR ( tinh quang ((tuan van) OR (tran van)) hien soat ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung san va kiem soat ) or ( tinh quang ((tuan van) OR (tran van)) hien soat ))*".
