A Chinese Odyssey 2 Pocket Edition can't go up because the phone is running out of memory. A Chinese Odyssey 2 Pocket Edition is an extension and expansion on mobile devices. The updated pocket version realizes the seamless interconnection between mobile devices and PC terminals. As long as the pocket version is installed on the mobile phone or tablet, you can log in to the original end-user account role, but it requires a lot of mobile phone memory. If you can't get on, you need to clear enough memory space of your phone first, and then log in again.
