Last summer holiday I wentto visit the museum in Haikou with my friends. In the museum, we saw many oldthings on show. We learned a lot about the history of Hainan from the museum.After visiting the museum, we ate some delicious food in a Chinese restaurant.We had a very good time. Besides, we also did different kinds of outdooractivities, such as swimming, playing basketball and so on. We found greatpleasure during last summer holiday.
