Which episode of Zhuang Hui in Iron Walnut was put in prison?

Let me show you the story introduction of the first 15 episode of Iron Walnut.

Tang San sent people to the state guesthouse to inquire about the troops fighting Long Da and others. Zhang Zhibao was sent to the emergency room by agents, and everyone was waiting for him to wake up, trying to learn from him what happened in national hotel.

He Tao and Zhuang Hui were also brought into the audit office at the first time, and were soon separated. Wang personally questioned He Tao, but found nothing.

Liu Bo came to Wang Feng 'an's office again, cleared He Tao's name. His purpose is to make He Tao grateful and let Well Lee go.
