It says Chinese wasn't included in the seven family of languages.

Yet, I, a english and cantonese speaker, couldn't help but notice these two words which sound similar in both languages.

Mother is "ma" in English, and also "ma" in Cantonese.

Father is "pa" or "dad" in English, and "ba" or "deh" in Cantonese.

Remarkably similar, considering both languages are considered by linguists to be practically completely unrelated.
