No. According to official website, the day of fun is the first bread chain brand founded by CJ Group, the largest food company in Korea. Inquiring about the profile of Duole Day Company, we know that this company is a legal company with complete qualifications and protected by law. The headquarters provided technical training and support before opening the store on the day of Duole. After a week's training, we can easily master the production technology of various baking products. Therefore, it is not a scam to join the store on the Happy Day.
