These applications not only simply copy native applications to HarmonyOS system, but also adapt and innovate in design and function. For example, National K-Song has added a virtual KTV function to the HarmonyOS system, so that users can enjoy the fun of KTV at home. In addition, some applications also support Huawei's multi-screen collaboration, intelligent split screen and other functions, which improves the user experience.

Tencent, Ali, Meituan, Netease and other big companies also announced their cooperation with Huawei, preparing to board the HarmonyOS system. This shows that the ecosystem of HarmonyOS system is expanding rapidly, and all major application developers are testing the "HarmonyOS system".
