The one I looked at is Mayun who is the richest man in China, and I looked at his Weibo which is one of the biggest social media in China. He is a trustworthy person, because he has had lots of speeches at many places including colleges and public stages. He never published a book, but there are many books talking about him. He has many valuable characters in different fields. Even though he has a lot of money, he never shows off it and wastes it. He even focuses on protecting the Earth. His company has a project that people can plant trees online by using his apps. When a user planted a tree, on his or her phone, Mayun’s company will plant a real tree in the real life. For example, the very recent post (https://weibo.com/2145291155/JpatS2D2J) that he posted is about environmental protection. In this post, he uses ethos to inspire people to take actions. In another posts(https://weibo.com/2145291155/JiwgmhTT6), he also uses ethos to let parents pay more attention on education of their children. Most of posts that he posted are very inspiring and calling people to take actions.
