How to change the value of the parent row and with it the child?

Question

MySQL

Hello, I have such a question, I need to use a query to change the value of the cell, which is the foreign key of the main table and at the same time change them in the child.
Example:

Main table:
Name
value1 Child

table:
Name
value1
value1
value1

Name is a foreign key.
Thank you in advance)

If this is a FOREIGN KEY with the ON UPDATE CASCADE option, then it will change itself when the value in the main table changes.
