Today I just have a presentation with the Informatics Department of the Ministry of Public Security (MPC), and  President of the Informatic Assosiation Vietnam, in order to give MPC a complete solution for using in their offices, brands, … but due to the misunderstanding each other a litle bit, so I did not prepare a successfully presentation, but with friendly talking, they promiss to welcome us for another presentation in some next few days. Not so bad though.
