(English version follows Chinese Part)
我大概从2003年开始，除了看父母订阅的期刊，也系统地给自己订阅自己喜欢的期刊，包括军事、航空、自然类的，虽然只是业余期刊，但也一种能够维持阅读量的重要方式，为我的知识储备提供了巨大帮助。特别是当时网络和计算机并不如今天发达，许多课外知识除了公共媒体，大概就是通过期刊了。也正是通过期刊，我意识到了“知识领域”的概念。
I started to subscribe and read journals for since 2003, for myself. Apart from those journals my parents subscribed, I keep reading about military, aviation and nature. Even though they are “hobby” papers, I did fetch tones of knowledge from them. Especially when it was the time that Internet and smart devices were not that popular. And I set up the knowledge structure called “knowledge fields” thanks to these journals.
想来自从读大学离开家以后，就没有非常认真地定量定期的阅读期刊，剩下的时间都在网络上获取碎片化知识了。阅读能力、知识获取效率都大幅降低。
Unfortunately I lost that habit in my undergraduate years, all I did are collecting fragmented knowledge. My abilities of reading and knowledge absorbing are degenerating.
近来决定还是要恢复一下阅读期刊的习惯。正好学校的网络可以通过各大文献库免费获取各种专业、业余期刊，求之不得。
It is horrible that a person lose his ability to read. I must find something to read in regular time and regular quantity. It is easy to fetch professional and hobby journals from journal database for free with my university authorization. Cool!
