On the morning of May 22, 2012, old friends Chen Younan and Chen Xianxian arrived at Hongqiao Railway Station at 6:10 p.m. by high-speed train from Xiamen to visit us in Shanghai. I took the bus 2 hours earlier to pick them up at the station. It was quite smooth all the way, and then arrived home more than an hour later. The old man put the newly cooked hot dumplings on the table, and everyone ate and talked. After a long separation, I was filled with feelings and endless words.
