Chinese Character in JSON code listing in LaTex returns errors

I use the following LaTex codes to show JSON in the document:

\begin{lstlisting}[language=json,firstnumber=1]
{"src": "123", "dst": "345"}
\end{lstlisting}

It displays fine. However, when I change the values to Chinese characters, it shows 3 repeating errors:

Improper alphabetic constant
Missing number, treated as zero
Missing = inserted for \ifnum

I have no clue what they are talking about.

Additional Information:

p.s. I'm using Overleaf online LaTex editor.

Solution

If you compile with lualatex or xelatex, you could use the following code to choose a font which has the Chinese characters you use. An overview of the available fonts on Overleaf is available at https://www.overleaf.com/learn/latex/Questions/Which_OTF_or_TTF_fonts_are_supported_via_fontspec%3F

% !TeX TS-program = lualatex
