I want to know the answer to the following question:
What is the name of the son of Chen Zheng?
All the background I'm provided with is that "In 677 (during the reign of Emperor Gaozong), Chen Zheng (陳政), together with his son Chen Yuanguang (陳元光), led a military expedition to pacify the rebellion in Fujian.". Is that enough to answer the question?
Answer: yes
