How did a street urchin from the film crew end up in a Northern Song Dynasty drama called "The

After Wan'er called the little girl closer, Jin Shuai said solemnly, "If you want your girl to recover quickly, you must remember what I'm saying. After you've wiped your girl's body, at dinner time, remember to give her some dog meat and bone broth. However, remember, you must wait half an hour before she can drink the decoction made from the large green root. Afterward, boil the large green root with three bowls of water until only one bowl remains, then you and the other girl should each drink half. In addition, every half hour, you should wipe your girl's body with warm water. As for how to divide the work, it's up to you two." When the quicklime arrives, use tongs to place it into the bucket. Do not touch it with your hands. Tomorrow morning, slowly remove the clear water from the top of the bucket and sprinkle it evenly throughout the courtyard. Inside the house, simply spray it lightly. Do not go out recently. Tomorrow I will send someone to place the necessary medicine and food at your door. This large green root should be given to your daughter three times a day, one bowl each time; the two of you should only take half a bowl each time. Also, remind your daughter to drink plenty of water, but the water must be boiled first and then left to stand until it is at a suitable temperature before drinking. Have you remembered everything I have said?”

“My lord, we have remembered.” The two women nodded gently and responded softly.

With a serious expression, Jin Shuai instructed, "You must arrange your time reasonably, take turns resting, and never overwork yourselves. Otherwise, if you become physically exhausted, you may also contract this disease." After saying this, he turned around, left one of his attendants behind, whispered a few words to him, and then set off on his return journey with the other two attendants.

At this moment, inside an oxcart on Zhuque Street, Jin Shuai thought to himself, "Today is truly an incredibly unlucky day! In modern society, chickenpox is nothing more than a matter of getting a few injections and being cured. But in this ancient era, people know very little about this disease, and it can even be fatal. Luckily, I ran fast. When I get home, I must disinfect myself thoroughly; it should be fine." With these thoughts in mind, Jin Shuai continued his leisurely journey with the oxcart. As they drew closer to the back gate of the Jin residence, the anxious figure of the Jin steward suddenly came into view. He paced back and forth at the back gate, and when he saw the oxcart carrying his young master, he was about to step forward when the attendant leading the ox stopped abruptly about 20 paces away. After Jin Shuai got out of the car and explained the relevant precautions in detail, the butler stopped and called out loudly, "The old master is waiting for you!" Upon hearing this, Jin Shuai quickly replied, "We need to finish our baths and disinfect ourselves before we ask the old master to meet us by the pool."

An hour later, sunlight streamed down the tranquil pond, making its surface shimmer. Jin Shuai walked slowly with light steps, his gaze drifting towards the pavilion. There, a middle-aged man who looked to be no more than forty-seven or forty-eight years old stood quietly. Undoubtedly, this was the grandfather of the original owner of this body. Thinking of this, Jin Shuai couldn't help but feel a little ridiculous—he himself had been over forty in his previous life, yet now he had to call this man of similar age "Grandpa"—it was truly difficult to utter! However, what could he do now? He could only sigh inwardly, expressing his utter helplessness.
