In 4 A.D. Wang Ping became the wife of Emperor Ping and he made her empress. However, in 5 A.D. Emperor Ping died and Wang Ping's father Wang Mang appointed as emperor a one-year-old infant Liu Ying for whom he acted as regent. Three years later, Wang Mang usurped the throne, declaring himself emperor of the Xin dynasty. He granted the deposed Liu Ying the title of Duke Ding’an and made his widowed daughter Dowager Wang of the Ding’an Duke.
During her father's reign, Wang Ping often claimed to be ill and refused to attend imperial gatherings. Wang Mang, believing that he could solve her unhappiness by having her remarry, changed her title from Duchess Dowager of Ding'an to Princess Huanghuang in 10 A.D. He also intended to marry her to the son of one of his important officials, Sun Jian. He instructed Sun Jian's son to dress well and accompany physicians to go visit Princess Huanghuang. She was greatly offended and would not receive any guests afterward.
Wang Mang was eventually overthrown, defeated by Han dynasty armies in 23 C.E. The people of Chang'an, who rose against Wang Mang as well, set fire to the main imperial palace, Weiyang Palace, and the fire quickly spread to the part of the palace where Wang Ping lived. She thought that she couldn't face the people of the Han imperial family with a clear conscience and then threw herself into the fire and died. Her father was killed shortly afterwards.
Wang Ping was a quiet and obedient young woman of great integrity.
Empress Wang was the wife of Emperor Ping. She had no children.
