近日，东南大学博士生导师陈洪兵教授在小红书上说：自从博士扩招，博士由考试入学改为考核入学后，博士生源质量明显下降，博士们根本不读书，水平比硕士还差。所以近年来他都是劝退想读他的博士的考生们，先想清楚再读博，宁缺毋滥。混个博士学位一点用都没有，纯粹浪费教育资源！
Second, there are fundamental flaws in the profit structure. Raw-material costs have long remained above 85% of revenue, reaching 87.5% in the first three quarters of 2025—well above the industry average. This was compounded by a 63.7% surge in selling and marketing expenses in 2024 and a 20.1% increase in administrative expenses; cost growth far outpaced revenue growth, keeping gross margin under sustained pressure. Third, there is a perception gap between the flagship “freshly hand-wrapped” selling point and actual operations. The company uses centrally produced, frozen ingredients delivered from a central kitchen, with stores only wrapping on-site—something that does not match consumers’ understanding of “handmade throughout the entire process.” Controversy over pre-prepared food has further eroded trust in the brand. In addition, the company also faces compliance risks: in 2023, 21.6% of revenue was processed via third-party payment channels, and issues such as unpaid social insurance contributions and deficiencies in property filings remain to be addressed.
