Shen Yin's natural face is indifferent, innocent, happy, sad... All make people feel cold, but Shen Yin doesn't think so... Ding Ning (nìng) is born with a smiling face, but every time he sees Shen Yin, he has a wronged face... Shen Yin found out that he was wrong, so he devoted himself to managing his expression day and night... Later - Ding Ning usurped him: "Stop laughing, you are too charming." (Shen Dinghua, also known as Ruixiang)
