Sorry, actually this article was first posted at 22:51 February 7 Beijing time on my subscription account on WeChat official accounts platform, the source you referred was posted on February 8 Beijing time, and at the end of the post you referred the original source('作者' and '来自') was specified. That is, the post you referred is plagiarized. And I learned a lesson here that I would not post my work both on my WeChat subscription account and steemit.
