Introduction to Wang Dalong Scissor Shop: Wang Dalong Scissor Shop is the leading scissor shop in Shanghai, and its products are very reliable. Founded in the third year of Jiaqing in the Qing Dynasty, it has a history of more than 200 years. The store's tenet is "three points for grinding and seven points for knocking", and it is quite distinctive "selling knives to open the mouth and selling scissors to shake the head". The dragon-patterned steel knife should be the treasure of the store. The blade is said to be made of thousand-layer steel and will not be damaged even if it is used for several years. In addition to scissors and knives, Shanghai Tang’s old-fashioned group heating tool "Tangbaozi" is also a nostalgic highlight here.
