   Suppose to the contrary that $p_1, p_2, dots, p_n$ is a finite enumeration
   of all primes. Set $P = p_1 p_2 dots p_n$. Since $P + 1$ is not in our list,

+/// #link("https://github.com/touying-typ/touying")[Touying] (投影 in chinese, /tóuyǐng/, meaning projection) is a user-friendly, powerful and efficient package for creating presentation slides in Typst. Partial code is inherited from #link("https://github.com/andreasKroepelin/polylux")[Polylux]. Therefore, some concepts and APIs remain consistent with Polylux.
+///
+/// Touying provides automatically injected global configurations, which is convenient for configuring themes. Besides, Touying does not rely on `counter` and `context` to implement `#pause`, resulting in better performance.
