In the fifteenth year of Tianbao's reign in the Tang Dynasty, Maweipo mutiny occurred. Yang Yuhuan escaped from the golden cicada and survived by luck. She ruined her appearance and changed her name to "Yang Xue". Carrying the top secrets and pain of the former imperial concubine, she lived in Luoyang, the eastern capital.
In Luoyang, she struggled to survive at the bottom of the city, relying on her extraordinary perfume-making skills honed in the former palace to gain a foothold in embroidery workshops, music halls and merchants. However, the aftermath of the fall of the empire and the shadow of power always follow. The Supreme Emperor Li Longji never gave up his crazy pursuit of "Going to poverty and falling to hell" until his death. His obsession aroused the suspicion of all parties - the suspicion of the new emperor Li Heng, the criticism of powerful ministers, the use and imprisonment of the mysterious masked man, the secret investigation of the old eunuch Gao Lishi, and the revenge of the aristocratic family - intertwined into a huge net, and she was involved in the whirlpool of life and death again and again.
While in exile and imprisonment, she met Liu Mingyuan, an idealistic prospector, and was forced to deal with the political chess game of the eldest princess Li Shiniang. After going through the fireworks in the market, jail, emotional entanglements and secret battles in the court, she finally faced the new emperor in the Zichen Palace. At the price of being permanently imprisoned in the "Snow Garden" and erasing the name "Yang Yuhuan", she exchanged for a complete end to her identity.
At the same time, the eldest princess revealed Li Longji's years-long painful pursuit after Maweipo and his deep regret until his death. After learning the truth, she used what she had learned throughout her life to prepare the "returning incense", and said her final farewell to the love that spanned life and death amidst the lingering smoke. Although she did not gain worldly freedom, she achieved nirvana in a desperate situation from a beloved concubine who relied on others to a "mystery" who relied on her own skills and will to protect her inner peace.
