How do you say "grandma" and "mother-in-law" in Cantonese?

If it is a child, it is called: Grandma is awkward; If it's a daughter-in-law, it's called grandma. But the tone is different from Mandarin.

If the mother-in-law calls her grandson like this, she will be tempted to read it twice. 1 time. If the old woman is called an ordinary person, it is called Mandarin.

Mother-in-law and grandmother are two different usages in Cantonese.
