After Rong Zhi was arrested, his family immediately entrusted a lawyer, Wu Danhong, because a scholar and lawyer who specializes in difficult evidence took the case for free out of the psychology of exploring this ancient case. However, when you feel that you have met someone from Nanchang detention center in Beijing, don't tell Cha that there is no such person. The case-handling organ then appointed a legal aid lawyer for Lao, so he did not intervene in the case in the first instance. The old family entrusted another well-known lawyer, Zhou Zhaocheng, but the case-handling organ did not let Zhou Zhaocheng intervene for the same reason. Old Rong Zhi's family still refused to give up and continued to entrust two other lawyers, but neither of them intervened in the case.
In the second trial, Rong Zhi's second brother entrusted Wu Danhong's lawyer again. At first, the court refused to let Wu Danhong be a legal aid lawyer, but later, it opened a channel for lawyers to ask Rong Zhi Sr's own opinion. After meeting the lawyer entrusted by his family, Rong Zhi personally signed off the legal aid lawyer and agreed to the lawyer entrusted by his family to defend himself.
