No one knows what Chi Mu said to Han Jingnian, he turned to glance at her, and they took a few steps down the stairs. Just as they reached the fountain, Chi Mu steadied herself against a street lamp at the entrance of the Beijing Hotel and adjusted her sandals.

What Xia Wan'an saw was actually like this -
Since it had rained in the evening, the temperature was somewhat low. As they left the Beijing Hotel, a gust of wind brought a hint of cold air.
Chi Mu, wearing a spaghetti strap dress, hugged her shoulders and shivered. Then she looked at the suit jacket on Han Jingnian's arm and said, "I didn't expect it to be so cold at night in Beijing..."
The moment she finished her sentence, her voice trembled.
Han Jingnian paused for three seconds. He looked slowly at Chi Mu who was "shivering" from the cold, wondering why she followed him after he left the dinner party earlier, and simply said "oh".
