Also, please note that according to the requirements of the GPLv2 license, any software modified or developed based on DragonOS must also be open-sourced under the GPLv2 license and must indicate that it is based on DragonOS. It is also necessary to ensure that users of these modified versions can easily obtain the original version of DragonOS.

You must make it possible for the developers of DragonOS to obtain the source code of your modified version through the same way from public channels, otherwise you will violate the GPLv2 license.
