Hello guys, The CLA signing is online at openeuler.org website. 中文版本： https://openeuler.org/zh/cla.html English version: https://openeuler.org/en/cla.html Please feel free to try it and give a feedback. Thanks very much. Once you have signed the CLA, when you push a pull request in the openEuler community, your pull request will be added a label named "openeuler-cla/yes". In opposite, your pull request will be added a label named "openeuler-cla/no" automatically. Best Regards, Edison Xiang
