Are sign language and Braille the same in different countries?

Braille is phonography. Although Braille in all countries is basically based on 2*3 grids, the meanings represented by grids are different in different languages. Braille in China is based on Chinese Pinyin.

Sign language is an ideogram, and one action represents a word. Although some words are expressed in the same way in different languages, the order of connecting them into sentences is different. Moreover, function words are often typed by phonetic means, which is even different in various languages.
