However, Duke Ling later deposed him and made his half-brother Ya the new crown prince, at the request of his favorite concubine Rong Zi.
In the fifth month of 554 BC, Duke Ling died after 28 years of reign, and the powerful minister Cui Zhu installed Guang on the throne instead of the new crown prince Ya.
The next year, with Duke Zhuang's support, Luan secretly returned to Quwo, the old Jin capital, and rebelled again.
Meanwhile, Duke Zhuang dispatched the Qi army to invade Jin, reaching the Taihang Mountains.
After hearing of Luan's defeat, the Qi forces retreated, taking the city of Zhaoge on the way back.
