While the around 6,000 common Chinese characters can be supported by the `CJK` package (or the `ctex` family of documentclasses) well, what if I want to type some (relatively) rare Chinese characters (it is said that there are about 60,000 Chinese characters in total) which, for example, appeared in ancient poems and documents?

For instance, today I tried typesetting the following characters 

> 
> 玕, 襜褕, 雰雰
> 
> 
> 

in a poem under the `CJK` environment (later I changed my documentclass to `ctexbook`), I can't see them in the output pdf document.

I believe there probably are some ways to handle this issue in LaTeX, but I don't know how to carry out these potential solutions to get my missing (but important) characters printed out. 

A google search leads me to a [reference](https://www.tug.org/TUGboat/tb24-3/wong.pdf) aiming to solve this problem. The solution therein looks promising in theory, however, I was not able to find the `HanGlyph` package described in this paper from CTAN so the implementation is still a problem.

It would be greatly appreciated if anyone could provide me with some guidelines (I am making a document that collects Chinese ancient poems. Therefore, the chance that I met these rare characters is pretty high.).

My code:

```
\documentclass[12pt]{ctexart}

\usepackage{xeCJK}

\begin{document}
美人赠我琴琅玕

美人赠我襜褕貂

欲往从之雰雰雪
\end{document}

```

My output:
