On the seventh day of Australia, in order to save energy, we went to a local group today. The second stop is the Puffing Bill train in Denton Hills. It has a history of several hundred years. Then it ran out of money. The government gave it to a group of like-minded old men to run it. Now it's a local scene. It's bound to punch in. What's the difference between an avant-garde train and a small one? Well, there's only one, the environment is good, the staff is nice, the car maintenance is good! From this, we can see that if we don't do something bad, it depends on whether we have the intention or not. In fact, the truth is the same for the environmental protection of the heavenly dynasty.
