Using standard Morse code, the most common method is to use Q code and English abbreviations. Chinese abbreviations are rarely used. If you use pinyin, the other person will also need to look at the pinyin to understand the Chinese, which is not an efficient way. Instead, choose a set of 4-digit Chinese codes that do not follow any pattern (some people say this started in the 1950s, while others say it began in 187x, and it always reminds me of the "four corners" code, which was introduced in 1925).
It can be seen that using pinyin for communication is not an efficient method; instead, short codes would be more efficient.😀Furthermore, when encountering words with similar sounds, it becomes even more inconvenient. While I have used this configuration before, I personally feel that it is not suitable for widespread use.
It also has advantages, as everyone knows Pinyin, but now Chinese codes need to be read from a book, which is inconvenient. Furthermore, there are different versions, and I have one with a codebook, which is quite historical.
