He is the last eunuch in China. He was purified at the age of 8 and entered the palace at the age of 13. He has seen emperors, empresses, and concubines, as well as wars, criticisms, and separations of life and death. A broken body, a palace wall for half a lifetime, and a life of loneliness. From the late Qing Dynasty to New China, he lived for 94 years, witnessing the collapse of a dynasty and the rebirth of an era. Others see him as a "living fossil", and he just wants to be a dignified person. When the roots were cut off, he still used his remaining body to hold on to the last glimmer of humanity. A true adaptation? A modern epic? The legend of Sun Yaoting, the last eunuch in China.
