Charles River is a river about 192 kilometers long in eastern Massachusetts, along which there are famous universities such as Harvard University, Boston University, Brandeis University and Massachusetts Institute of Technology. At Boston's entrance to the sea, we arrived at the Bank of Charles River in September of autumn. The bank is a very beautiful park. There are many cyclists and runners in the park. There is a cherry blossom Avenue in the park. These cherry trees were sent to the United States by Japan more than 100 years ago. Almost all of them are planted here. The cherry blossom trees are very tall and can be imagined in the cherry blossom season. How beautiful it is here!
