Mok King Yeung is a fireman stationed in the Pok Fu Lam Fire Station. He wanted to be a fireman since he was a kid. He thinks that in the physical fitness test, the "squat" exercise is the hardest to pass. Apart from the physical fitness test, Fireman Mok said, "The interview session is also important. It is because the examiner will assess your personal character to see whether you are suitable and have passion to be a fireman." Successful candidates would receive training in the Fire Services Training School. When scolded and punished by the instructors, Mok kept blaming himself. However, once he had overcome the obstacles and completed the tasks one by one, he regained confidence gradually and began to feel a sense of satisfaction. Mok's first operation was to rescue some people trapped in a lift. The experience made him realise a successful rescue operation is only possible when the team works together closely.
