Before taking the train, I heard that Sri Lanka's train delays were very high. Looking at the shooting time, I waited at the railway station for more than two hours and then drove very slowly and slowly along the way. While waiting at the railway station, there were many trains coming and going. The local adults and children greeted us warmly. They felt like they were back in China in the 1980s. They were sitting on the green-leather train and waving to the strangers who were parked on the opposite train. The boy in Fig. 4 sees me playing a monkey to amuse me; there are many stray dogs here, but they look good, they are thin.
