Baoyu confessed his identity as a spy to Guan Xiaozhi on the 15th day of the first lunar month, which was the night of the Lantern Festival. At that time, Baoyu and Guan Xiaozhi were admiring the moon together. Baoyu suddenly felt someone approaching him from behind. He turned around and saw a person in black standing behind him. Baoyu felt a little nervous, but he still smiled at the man in black and asked,"who are you?" The man in black did not answer Baoyu's question but told Baoyu that he was sent by Guan Xiaozhi as a spy. Baoyu was a little surprised but he still nodded to show that he knew the importance of this task and was willing to accept the challenge. Then, Baoyu and Guan Xiaozhi admired the moon and talked about their lives and feelings. Baoyu confessed his undercover identity to Guan Xiaozhi and expressed that he hoped to become Guan Xiaozhi's friend and ally to fight against evil together. Guan Xiaozhi was very happy to hear Baoyu's words. The two of them hugged each other to celebrate this unforgettable night.
