How many characters can a China, Japan and Korea short message have?

The transmitted characters include Chinese, Japanese, Korean and other double-byte characters, so the 8-bit encoding of 2 bytes is adopted, so 1 120÷8÷2=70 characters, that is, at most 70 words are transmitted (a space or punctuation mark in the short message content is also counted as a word).
