Hong Kong Lesson One （《香港第一課》）, this series of articles are written by Leung Kai Chi (梁啟智) and posted on matters.news for free.
China government has blocked matters.news. So, it's a little difficult for netizen in mainland China to visit matters.news. I want to share these series to people knowing nothing about Hong Kong, to people misunderstanding Hong Kong and to more people daring to know the truth.
So, I make a PDF version.
Now, Hong Kong Lesson One （《香港第一課》） has been published. https://www.books.com.tw/products/0010844637
