Because Shen Aojun has no schedule.

In 2003, due to the strong response after the broadcast of "Xilai Le", Hebei Cangzhou and CCTV, producer, editor and author Zhou Zhentian had plans to discuss the creation and filming of a sequel. In April 2009, the producer of "Xilai Le" was preparing to shoot a sequel and had contacted Shen Aojun. When filming started on December 7, 2011, Shen Aojun was participating in the filming of "Da Shun", so he was unable to participate in the filming of "The Legend of Miracle Doctor Xilaile".

In the end, it was Jin Yuting who took over the role of Sai Xishi played by Shen Aojun in "The Miracle Doctor Xilaile". She used her own artistic attainments to carefully figure out the image of "Golden Style Sai Xishi".

The Sai Xishi played by Jin Yuting is graceful, polite, neither humble nor overbearing. She could follow Xilaile and be exiled thousands of miles away, treat the hard days as good ones, cook delicious food for Xilaile in different ways, and carefully protect Xilaile and prevent him from being wronged. But whenever Xilaile was confused or lost his sense of proportion, she would unequivocally control him.

She is the backbone of Xilaile. She often wakes up the dreamer with one word when Xilaile is lost and has no idea. She was also jealous and unhappy when Jin Shanjiao appeared, but she was able to assess the situation, not only leaving a step for Xilaile, maintaining the man's self-esteem, but also silently drawing boundaries.
