Is it because we only know Baidu? See if it's the same movie as Love is Echoing? It's also a film about the relationship between mother and son. Is "Mother and Child Affection" broadcast by Pearl Theater in Langfang City, Hebei Province on 20 18 the same as "Love is Echoing"? After reading the outline, it's almost the same (all children don't like learning and contradict the teacher, and their mothers don't understand and become sensible)
