Wheatland trip

1.I think it is a very meaningful trip. I feel this trip is very interesting.
2.I learned a lot about American history. I also have a certain understanding of the Americans family life style of the 18th century.
3.I am surprised that we visited the former residence of a former president.
4.I want to know more about the background of the 18th century in the United States.
5.At that time, China was in a feudal society. The ruler's incompetence led us to sign many unequal treaties such as Treaty of Tientsin and more.
