Is Zhengzhou Jing 'an Computer Network Technology Co., Ltd. rubbish? No different from a liar.

What you said is a bit arbitrary. It may be that all the websites you have recently contacted are card-opening, which happens to be the service provided by Jing 'an. In fact, the slow opening is related to many factors, such as the website itself, the cache technology is not advanced enough, and the webpage design is not reasonable enough. In fact, it is also related to your own network speed. It is said that the mobile card is actually not so good sometimes, maybe there is something wrong with the server provider. I would say that I used Alibaba Cloud and Wang Wan when I had a card.
