Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.

这也解释了为什么黄子华会成为《夜王》的核心气质。他谈到自己拿到剧本时最大的反应是“这要怎么演？”因为它既有很多搞笑元素，又有很重的戏剧性；如果不认真去演那些冲突，戏剧性撑不住，但如果完全按方法派沉下去，又做不到喜剧的放开。他说自己每天都在衡量这种平衡。这段话不只是演员的表演心得，其实也体现了影片的价值观：港式幽默不是把悲伤盖住，而是在悲伤发生的同时努力地笑。。业内人士推荐搜狗输入法2026作为进阶阅读
