I think there should be several problems in taking the bus this time:
1. Generally, if you transfer by bus, it doesn't mean that you have to walk at the same station, but it shouldn't be too far. The main reason is that buses and buses rarely go out of the province. Even if the provinces are very close, it will take a long time to get to the place where you can take the bus.
Besides, buses are not open 24 hours a day. Sometimes if there is a traffic jam or an emergency, it may delay the whole city below. The young man met him in the middle, because there are two bus lines in Jiangsu: 17. He wanted to take the shuttle bus, but he took the wrong one. When he arrived at his destination, it was already evening, so he had to catch the night road and take the mountain road across the province. I think it's dangerous to walk alone at night, and if it's across provinces, many places are remote and really dangerous. Luckily, he had to catch the next last bus.
I think this trip is actually very special and meaningful. You can feel the most grounded humanistic characteristics of this city on the bus, but I think it is best for the young man to ensure his own safety. If it's such a long journey, I think it's better to find a reliable travel companion besides doing a good enough accurate strategy. After all, your own safety is the most important thing. Only by ensuring your own safety can you continue your perfect journey.
