I am not a content porter

I, agathakuan, am the same person as the author CHTA-TE KUAN, who is known as agathakuan on CSDN and the owner of the Blogger site "Programming notes". 

CSDN: agathakuan-CSDN博客

Currently, I am expanding my publishing platforms and plan to publish articles on CSDN. Therefore, I am transferring some content from my original Blogger site, "Programming notes," to my CSDN blog under the username agathakuan. 

In the future, I will publish the same content in English on Google Blogger and in Chinese on CSDN. All articles are originally created by me, and any content cited from other sources will be properly referenced with the URL.
