Spelling （拼法） is the set of rules about the usage of graphemes to write a language. In Chinese, the characters are graphemes, so spelling refers to how characters are used together to spell words. Use this tag for questions about usage of particular characters instead of others to represent sounds.
In alphabetical languages, graphemes are the single letters and spelling, as part of orthography, regulates how letters are used to write words.
In Chinese, characters cover the role of graphemes. Thus spelling may refer to choosing the correct character to represent a certain sound. For example, in the word 中国 is spelled using precisely the character 中 (and not 钟，and not 终) together with the character 国。
This tag is for questions related to the choice of the correct characters to render Chinese sounds in writing.
