What are the jokes about taking the train?

Once upon a time, a hillbilly finally transferred from the country to the city to visit relatives by train. During his stay in a hotel, he saw a mosquito net hanging on the bed and asked the waiter how to use it. The waiter replied: put it down and you can use it. So at night, she put down the mosquito net according to the waiter's instructions (but she didn't know how to open it), and stood in the mosquito net on the bed all night, muttering to herself that the city people were so strange that they stood and slept! Finally, when I arrived at my relatives' house, they asked her what kind of transportation she took. She grabbed her head (she didn't know what a train was) and said word for word: I came in a big box! Relatives were blindsided and were about to ask again when the hillbilly further explained that there were several big boxes connected together. .......
