Yu Chengdong: The Harmony operating system has an annual investment of over 10,000 people and research and development costs reach hundreds of billions.

Yu Chengdong said that the development cost of HarmonyOS is very high, with over 10,000 people invested each year for six years, totaling hundreds of billions in research and development costs. The code consists of 1.3 billion lines, most of which were developed by Huawei, with some contributed by ecosystem partners after being open-sourced. However, this investment is extremely worthwhile for the country, as all smart terminals and machines can be solved using one operating system.
