Hello friends, a few announcements as follows:
Only articles about diet and climate change are left for this reopening website, for many previous articles are not relevant to the current crisis we are facing.
The contact form page and the comment section are closed, because I am too busy to reply or communicate with you. Please bear with me on this behavior.
Some articles have to be republished due to site changes or mistaken deletions, which can cause the link to fail. Those who need them can reconnect again.
A new column is created: words for all. Sometimes I catch some questions and will respond publicly.
I cannot write and update oftentimes. The main reason for reopening is to make it easier for people who are in need to use the information of this site for teaching materials and etc.. If some information is too old, you need to find new ones for supplement yourselves.
Thank you for visiting this site!
