The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.

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.
