Xiao Fan, the director of a clothing factory, has been ordering lunches from Hongyun Restaurant for his employees for a long time, but his boss Liu Hong kicked him out because he disliked the "trivial" orders. Xiao Fan instead chose the newly opened Chengxin Restaurant. Its owners, Zhang Cheng and his wife, were simple and sincere, and the food was of high quality and delicious. Xiao Fan not only signed a long-term contract, but also paid for meals in advance to support its development. But Liu Hong was deceived by gullible fake big customers, and her shop closed down, and she regretted it in the end. This turmoil proves that integrity and structure are the keys to long-term business.
