Welcome Liu Zixi (劉仔细 - hope tones are correct). Looking forward to your contributions. You might consider writing an article on use of Fedora in China - most of the articles at present are for English speaking audience, but this may be an opportunity to practice your writing. Setting up social media applications such as QQ, Wechat may be of interest to Fedora users. An overview of Open source software in China would also be great. See https://fedoramagazine.org/ and in particular https://docs.fedoraproject.org/en-US/fedora-magazine/writing-a-pitch/
