I had something to do this morning and went out of work. At about three p.m., my colleague called me to go back to the company to help me go to the mall to buy a adapter. He sent me the style and model with his cell phone, just about the end of my side, so I went to the nearby mall. To help colleagues buy his adapter, in fact, I still understand a little about adapter, although there is no major but a lot of styles and models I still know, because a company in the previous in the production and assembly of adapter, although I did not take responsibility for the case but it is often seen, And then there’s probably some understanding.
