It seems that releasing HarmonyOS for the first time also says all self-developed? Now it's saying this again?

On October 22nd, the first domestic mobile operating system - Huawei's native HarmonyOS was officially launched. This is also the third largest mobile operating system in the world after Apple iOS and Android. According to information, previously released HarmonyOS has been forced to use some AOSP open source code as its foundation due to the system base still using parts of the AOSP open source code, which made it incompatible with some Android applications. The release of the original HarmonyOS marks a significant improvement in the system base, smoothness, performance, security characteristics, and self-controllability of the system.
