Recently, @Kecun Xiaojiang, a Weibo account verified as a WeChat employee, announced that on June 6, the HarmonyOS PC version of WeChat had started inviting users to participate in beta testing. Testers are required to provide their device's SN (serial number) for registration.

Someone asked: "Is it cross-platform developed like QQ? Can it at least match the functionality of the Linux version?" @Kecun Xiaojiang replied: "Yes, it's cross-platform developed."
