As you can see, not only in VN but also many coutries around the world, many kinds of animals are strictly trained to do tricks: riding bicycles, play with balls, etc just for fun. They have suffered terrible training, they were seperated from where they belong to : the wildlife. Kids can laugh when they see animals doing tricks, but it's not good at all, because that means we are indirectly teaching them to consider animals as toys. Obviously, they're NOT! Let's sign and suggest Mr President of Vietnam to have a strict law forbidening using animals for circus like China did, and also to release these poor wild animals, send them to where they belong to.
