Official Naming of the Characters (Hanzi) in Mandarin Chinese Is there any official naming of complex (not the basic ones) Chinese Characters in Mandarin Chinese.

For example, I know that the character 博 is pronounce in Pinyin as:

bó

But If I were to, address (the name of) this particular character, and not intending to address its pronunciation, what name should I use? (example:the letter W is pronounce as "w" as in "ˈwɔːtə(r)" for the word water in the IPA of BrE but the letter itself is named (referred to as) "double u")

Note: Please add the resources link for this. I'm at a level of a beginner so please add some pinyin in your answer so that I can read it.

Generally, there is no name for a single character in Chinese. Or you can say the name is the character itself, but then there are too many duplicates when you only have the reading.

To address a single character, there are often two ways, one is to describe how it is written, one is to put it into a word.

Take "博" as an example. You can say that it is the "bo2" with a "十" on the left, which is describing how the character is written. Or you can say it is the "bo2" in "博士"("博士的博"), which is putting it into a word.

For some characters, there are generally accepted ways to describe them. For example, "李" is often referred to as "木子李", and "张" is often referred to as "弓长张".
