     After staying in Beijing, it was time to go to Shanghai. So I decided to take the train to Shanghai and stop

halfway at Tai'an for a day to break up the trip and climb Mount Tai. The train arrived in the city at 10 pm.

It was late and I was tired. I started to walk around the city to look for a hotel, but I couldn't find a reasonable(合理的) one. Something was strange. There were so many Chinese tourists walking somewhere. I finally

followed them to see what all the excitement was about. As it turned out, they were all climbing the mountain

to reach the top by sunrise. What a crazy idea!

     I later found out it was the thing to do, so having no luck with hotels, I decided I had better join them. And

maybe because of the dark, I didn't have to pay for any entry fees (费). Of course the first thing was to find if

the mountain had a wall around it. Of course it did. And the second, it had a paved (用砖铺的) path and road

all the way up to the top. Anyway, I ran up the mountain and made it to the top by about 4:30 am. I relaxed a

little and watched the sunrise. Nothing was special. Everyone was cheering so I guessed it was worth it.
