This activity is very meaningful, so our parents took care of us, bathed us and cooked for us when we were young, so we can also experience what it was like for me to take care of my parents and their hard work. You can also give a second chance to be filial to your parents. This activity is ok. You can pass on some cultural traditions of filial piety to your elder, China, so that students can feel it with their own hands, not just on paper. Students can also gain some experience in this activity, and practice is the most important, and practice can give them real knowledge.
