21.A self-service flower shop operated by a college student in Beijing is attracting many young customers,Chinese media reported. Different from traditional shops in the capital,the young storekeeper surnamed Wang opened the first self-service flower shop where people can select flowers and pay via mobile payment systems including We-chat and Ali-pay. Born after 2000 and a lover of literature,the young man said "he begins the startup(創業) because it will not take up his time". "Besides,people can go to flower shops at any time," he added. "I cannot focus on reading when I have to serve customers." So Wang opened the self-service flower shop after doing market research. Most young customers like shopping in a free environment,and hate promotion(推銷) from clerks,he explained,adding that customers can have their questions answered about the names of flowers through mobile Apps. Even though there is no shopkeeper,the operation has attracted many young customers and proved to be a success,at least for now. Although he does not sell flowers in the shop in person,Wang said he would go to the shop at odd intervals to take care of the flowers though he couldn't afford it full time. "It is a business with a little money,and it can't cause a huge loss if a burglary (偷盜) happens," he said,adding that he trusts people.
