Message from the Chairman

We live in a gradual environment. If we are too numb to the gradual process, it will leave a sudden disaster for our children and grandchildren. We must use technology to accurately measure this change, use the call of the soul to alert people in reality, and use all our consciousness and intelligence to guard our own homeland and avoid the disappearance of human civilization.
——Lin Xuanxiong
