Black Friday is celebrated on the first Friday after Thanksgiving in the United States, and it is also the beginning of the traditional shopping season. The traffic is very heavy on Black Friday. On that day, the shop opened early, but closed late. On Black Friday, many people go shopping all day, because businesses make a lot of money that day. In many cities, people line up in front of the store hours before it opens. Electrical products, clothing and toys are all on the discount list. Many people use this day to buy Christmas presents for friends and family. Some people buy goods at low prices and then sell them online at high prices. Personal opinion, for reference only!
