Biography
In April 184AD the eunuchs Zhang Rang, Zhao Zhong, Song Dian, Guo Sheng, Xia Yun and Duan Gui were all enfeoffed as marquises and treated with great favour. Zhang Rang and Zhao Zhong were referred to as "father" and "mother" by Emperor Ling and from this moment on the eunuchs grew very confident of their influence. They built themselves great houses that rivalled the Imperial Palace.

On one occasion, Emperor Ling wanted to climb the Observation Terrace in the Palace of Perpetual Peace. From this tower it would be possible for the Emperor to see the eunuchs' houses. They became frightened and sent harem official Shang Dan to say:

"The Son of Heaven must never climb high, for if he should do so his people will be impoverished and scattered."

The Emperor never climbed another tower after this.
