Kudi Liuli (played by Guli Nazha) was born in the An family, which is known as the No. 1 Golden Needle. Her mother An's embroidery skills are exquisite and is known as the No. 1 needle in the world..An family was framed by Zhuo Jinniang (a certain character) of the palace's Shangfu Bureau because she held the golden needle that represented number one, and unfortunately died in the palace.Before she died, An entrusted Liuli to the care of Sun Decheng (a certain character) in the palace.Sun De became convenient and took care of her, so he disguised Liuli as a man, and from then on he was known as Doctor Dou.

Ten years later, Zhuo Jinniang discovered that Medical Officer Dou was suspicious, suspected that she was An's daughter, and wanted to persecute him.Sun Decheng was worried that he could not protect Liuli, so he sent her to make a living outside the palace.Outside the palace, Liuli accidentally met Pei Xingjian (played by Xu Weizhou). Pei Xingjian helped Liuli many times, and the two fell in love with each other.

When Sun Decheng went out of the palace to see Liuli secretly, he was caught by Zhuo Jinniang's people.In order to rescue Sun Decheng, Liuli went to the palace to rescue Sun Decheng regardless of the obstruction.Zhuo Jinniang took the opportunity to persecute Liuli and gave her a poison.In order to rescue Liuli, Pei Xingjian gave the first golden needle to Zhuo Jinniang.This move made Liuli conflicted with him and unable to forgive him.At this time, Pei Xingjian revealed the origin of the two: they had actually known each other since childhood.When Liuli fled, she entrusted the golden needle to him, who was also a child.In addition, Pei Xingjian also revealed that when Liuli went to the temple to ask for a signature, he secretly helped Liuli to choose the signature.

In order to make up for his debt to Liuli, Pei Xingjian gave her his jade pendant as a companion.He risked his life and went to the cliff to get herbal detoxification for Liuli.With the joint efforts of the two, evidence of Zhuo Jinniang's persecution of Liuli's mother was finally found.The emperor ordered Zhuo Jinniang to be sent to prison to die, and Liuli's mother Zhaoxue died because of her injustice.Kudi Liuli has since become a master of Shangfu Bureau.

After Liuli and Pei Xingjian went through all kinds of things, they finally got the emperor's marriage grant, and they finally got married.On the wedding day, there was a lot of joy, but this joy did not last long before the storm around them was about to come.In the palace of the Princess Linhai of Hedong Gongfu, a conspiracy is being planned to seize Pei Xingjian's family property.When Pei Xingjian was young, the eldest princess took charge of the Pei family's property. After Pei Xingjian got married, the eldest princess was forced to return the property under pressure, but her desire to seize it never calmed down.

Before Pei Xingjian married Liuli, he had married a woman named Lu Qiniang.Rumor has it that Lu Qiniang died of exhaustion because she worked so hard for the Pei family, and that Pei Xingjian and Lu Qiniang had an unusual relationship, and they could not help each other.Now that Pei Xingjian was getting married, the eldest princess had already taken precautions and asked her daughter-in-law Atui to find a maid named Yunu and send her to Pei Xingjian's house.When Pei Xingjian heard the sound of the flute, his expression changed drastically, and he knew that the maid sent by the eldest princess had arrived.Everyone knows that she is a maid in name but actually has ulterior motives.It cannot be beaten, scolded, or sold, but it must be provided properly.But these are not surprising enough. What is surprising is that Yu Nu has the same face as Lu Qiniang.Even though Pei Xingjian was mentally prepared, he couldn't help being surprised when he saw Yu Nu.

After Liuli understood the situation, she took Pei Xingjian to visit the eldest princess. On the surface, she wanted to thank the eldest princess for the reward, but in fact, she wanted to get Yunu's slave purchase deed to prove her identity.But the eldest princess did not give it to Liuli on the pretext that the slave contract was lost.Even so, Liuli couldn't refuse the reward from the eldest princess, so she had no choice but to take Yu Nu back.

Every day Yu Nu would play the flute in the rain pavilion, and Liuli, who was painting in the room, understood that this was deliberately disturbing her mind, just to make her and Pei Xingjian feel bad.But although she had seen through everything, she also knew that as long as she loved Pei Xingjian, suspicion would arise.

Liuli's indifferent performance also made the eldest princess feel a little admired, and felt that compared with Lu Qiniang, she was still more difficult to deal with.In order to break Liuli's calmness, the eldest princess deliberately sent Atui to invite Liuli to the temple to pray together, leaving Yunu to serve Pei Xingjian at home.It happened to rain heavily that day, so Liuli and his party were unable to go back, giving Yu Nu a chance.Yunu looked at Pei Xingjian who returned home from court in the rain and took the initiative to show his courtesy.

Early the next morning, Liuli returned home and asked the doorman about Yu Nu's situation yesterday, and learned that Yu Nu had not returned after going out.
