Yixing acted so well you would've thought he is a father in real life. The kid is also brilliant. They both embodied their roles 100% which is why the film is moving, it felt so pure and sincere. The fact that the majhong actors are actual deaf makes it more realistic, I am happy they got this opportunity to film a movie. Lay Zhang, your choice of role is always well-thought. Thank you for showing the world that diversity and inclusion is important in the society. This is a must-watch. Go give it a try.
