You can try but you must be careful

If you take a closer look, Hong Zheng was riding his tricycle front-side back. After he starts concurring the standard way of riding the bike, he takes the challenge to try the new way. At first, he asked me whether he can sit in this way. Initially i told him cannot. After a few days , he asked the same question again and i kind of re-think why not let him try as we should always learn from trying. So, i told him you can try but you must be careful. At first, he was also doing it very carefully but now, he just sit on it like sitting the normal way.
