Whether it is reliable or not depends on your own judgment. It is true that packaged papers are basically unreliable. The so-called agent just helps you sort out the filing materials or you have some unsatisfactory conditions. They try to make up for it (such as seals, achievements, papers, patents), and then participate in the annual review and unified filing through formal channels. After it was passed, there were public documents in official website. It's true. If you promise to have a small channel to review at any time or publicize it on some inexplicable websites, it must be false. There is a quota limit for the evaluation of senior and intermediate titles in the province every year. There is no such thing as a small channel, unless you find a defense judge, this is the real channel.
