I have a good friend who is engaged in the design work of adapter. I am very busy every day, sometimes I work late at night. In fact, the people who do the design know that they often work late, sometimes even all night, and friends engaged in adapter design for many years. Now it’s a bit of experience so the work is generally easier to finish. He mentioned that he was always a day when he started to set up this line of adapter. Work has been finished, even sometimes busy words don’t even know, only know that every time the completion of the work is already late, but that time still learned a lot of things, their ability has also been greatly improved.
