Ctheorems

Touying 能够与 ctheorems 包一起正常工作，你可以直接使用 ctheorems 包。

其中，你还可以使用 #set heading(numbering: "1.1") 为 sections 和 subsections 设置 numbering。

#import "@preview/touying:0.5.2": *
#import themes.university: *
#import "@preview/ctheorems:1.1.2": *
#import "@preview/numbly:0.1.0": numbly

// Theorems configuration by ctheorems
#show: thmrules.with(qed-symbol: $square$)
#let theorem = thmbox("theorem", "Theorem", fill: rgb("#eeffee"))
#let corollary = thmplain(
  "corollary",
  "Corollary",
  base: "theorem",
  titlefmt: strong
)
#let definition = thmbox("definition", "Definition", inset: (x: 1.2em, top: 1em))
#let example = thmplain("example", "Example").with(numbering: none)
#let proof = thmproof("proof", "Proof")

#show: university-theme.with(
  aspect-ratio: "16-9",
  // config-common(handout: true),
  config-info(

    subtitle: [Subtitle],
    author: [Authors],

)

#set heading(numbering: numbly("{1}.", default: "1.1"))
