There are shopping malls and supermarkets in Ginza (including Uni-President Ginza), supermarkets in He Jiong and RT Mart. You give it to the teacher, which belongs to the teacher-student relationship. There is no need to be too noble, and students' spending power is limited. I suggest you apply for a shopping card in RT Mart Supermarket, because RT Mart Supermarket is relatively large, with storefronts in several districts, and the environment is very good and affordable, which is suitable for ordinary people to consume. The face value is 200 yuan, 300 yuan, 500 yuan, 1000 yuan.
