I've heard about the escalator from Central to Mid-mountain in Chongqing Forest, where Liang Chaowei took the escalator to work. Afee took a peek at Liang Chaowei's house and sneaked in his heart. He was delighted to see the escalator extending to mid-mountain. He didn't marvel at the designer's ingenuity. On both sides of the escalator were towering residential buildings and shops. Many foreigners came in and out of many restaurants. People later learned that this was an escalator built by the Hong Kong and British governments to improve the traffic on the hillside. Many sights passed by. Think of the lines in the forests of Chongqing. Every day you have the chance to pass by with others. You may know nothing about him or one day he will become your friend or confidant.
