Ladies and gentlemen, good afternoon. First of all, let me express our thanks to you for coming to the opening ceremony of our new branch office.
    This branch is the 25th office we have set up so far. We are very happy that we have finally opened a branch in this city. This branch, we believe, will help improve the local economy. And our company will in turn benefit from doing business here. We promise that we will provide the best service to our customers. And, of course, we need your support and cooperation.
