Due to her intelligence and ability to deduct problems, Xiao Shanming planned for her to work under Lu Xingguang's team after graduation. However, Xiang Wenzhou left the police force due to the incident five years ago and has since never appeared until she came back to track the incident's truth.

- Cheng Jinghao is known to have skipped from training right to Xiao Shanming's class. When Cheng Jinghao joined the police force, the A-9 Guru Group was only just developing, so he became the first student in the group. At first, Xiao Shanming was unaware of Cheng Jinghao's abilities and was skeptical of the police chief's recommendation, yet he came to recognize Cheng Jinghao as his student. Cheng Jinghao later formally left the police force and started his own group of three.
