Yuanji Yunjiao has also run into a growth bottleneck and has kept trying to break through. On the one hand, growth has been heavily dependent on store count. In the first three quarters of 2025, per-store revenue efficiency fell 4.3% year on year, while average spend per order dropped from RMB 26.1 in 2023 to RMB 22.8. In lower-tier markets, the company also faced challenges such as pricing that is perceived as too high (an average of RMB 23, close to the upper limit of the price band in lower-tier cities) and difficulties in flavor localization—its southern-style, fresher and slightly sweeter taste profile has not been well accepted in lower-tier northern cities.

Poor software quality already costs the U.S. economy $2.41 trillion per year, according to a 2022 study by the Consortium for Information & Software Quality. That number was calculated before AI began writing a quarter or more of new code at leading companies. Chris Lattner, the creator of LLVM and Clang, put it bluntly: AI amplifies both good and bad structure. Bad code at AI speed becomes “incomprehensible nightmares.” As AI generates an increasing share of the world’s critical infrastructure (financial systems, medical devices, defense, transportation), unverified code becomes a systemic risk, not just a quality problem.
