What is the episode of Xiao San sending an ID card to Shang Beijing?

In order to test whether Shangjing really cares about himself, Jin Ling stopped Shangjing's car and said that he had left his keys at home. He wanted to stay at Shangjing's home for one night, but Shangjing said that it was inconvenient to stay at his home, so he opened a room for Jin Ling in the hotel. Shang Beijing settled Jin Ling and wanted to leave. Jin Ling kept Shang Beijing on the grounds of discussing the children, but Jin Ling didn't know how to test it, so he called his best friend for help. While she was on the phone, Shang Beijing quickly slipped out of the hotel. Shang Beijing's ID card was left in the hotel, and Jin Ling went to his house to return it. He also mistook the direction in the room for Shang Beijing's daughter, and told Jin Ling that Shang Beijing had been divorced twice, which suddenly frightened Jin Ling. Jia Fu once again told Jia Yuanyuan that his biggest regret was that there was no third generation, and Jia Yuanyuan hoped to satisfy his wish.
