I think the fundamental problem of china-us trade is the education level in science and technology. Countries have to be open to have a future. however opening up must be to keep fit and the ultimate goal is to have a cultural quality. This is likely to be a long-term battle for us. We didn't prepare just to fight against a short-term assault. The longer we fight the stronger we are. I am not worried. Now my daughter is very optimistic. She is studying five to six courses by herself. She plans to obtain a doctorate degree in prison. She gets quite busy. In Vancouver the house arrest is guarded by the police. But it's not imprisonment. Life is still free. we are completely in the right and the incidents have become sensational. The headline of Canada's largest newspaper said the arrest of Meng Wanzhou is an example of nations violating laws. That's equivalent of China's people stating. If we are not in the right, there will not be reports like this.
