HarmonyOS has undergone six years of intensive development, involving an annual investment of over 10,000 personnel and research and development (R&D) costs totaling tens of billions. The system boasts a code base of 130 million lines, the majority of which are proprietary to Huawei, while some originate from open-source ecological collaborations. Yu Chengdong emphasized that this system holds immense significance for the nation, capable of unifying the operating systems across all intelligent terminal devices.
