Zhong Jixian and other cast members attend a rehearsal, Jan 27, 2015. Each ceremony last 70 minutes and "I have to fully concentrate during the process, and to keep the word 'piety' in my mind to help me act in a solemn, pious manner," said Zhong. Zhong lost 3 kg during the five ceremonial days of 2010, when he started playing the part. "I had to pay attention to every detail when acting like an emperor; to walk with long strides, ascend steps and salute the god," he said. [Photo/IC]
