jekyll blog(minimal-mistakes thema) has a space to introduce myself.

I want to write on two lines in this space.
For example
hello
world
I know that to edit this page, i need to touch the _config.yml file.
# Site Author
author:
name : "Choi Young-jin"
avatar : "/assets/images/images/avatar.png"
bio : "**^^**" <-----------Parts to change
42 intra ID: yochoi
location : "Seoul"
email : "amateur.toss@gmail.com"
links:
- label: "Email"
icon: "fas fa-fw fa-envelope-square"
# url: "amateur.toss@gmail.com"
- label: "GitHub"
icon: "fab fa-fw fa-github"
url: "https://github.com/amateurtoss"
The escape character does not work.
bio: "hello\nworld"
What if I want to show the string in two lines?
