Hello, I want to ask why the app of Huaxia Dida Education Network can't be used. Due to network problems, the app of Huaxia Dida Education Network cannot be used. Huaxia dida education network app is an online self-study education platform, which is used online. When the connected network signal is not very good and the network speed is slow, it is easy to open the app and the page cannot be loaded. Therefore, Huaxia Dida Education Network app cannot be used due to network problems.
