Franklin's former residence is the business card of Philadelphia, where you can see a strange building, a white steel frame, outlining a house, which is the original site of Franklin's residence. As a result of a fire in the 19th century, all the houses were destroyed. In order to keep the most primitive state, people built the building and told you that it was Franklin's former residence. There is also an underground museum in the courtyard, which shows some documents of Franklin's life and his inventions (lightning rods are from his hands). Franklin has made the greatest contribution to the United States, but he disdains his reputation, donates most of his property before he dies, invents countless but never applies for patents publicly... Franklin is the greatest American indeed! Very positive energy, very educational significance, especially for young people, I must buy a Franklin's biography seriously after I return home, young people should study hard. In addition, the form of the former residence is also very special and refreshing. Some former residences in China should also learn this form. It's worth visiting and studying.
