Can a criminal detention lawyer bring something with him when he meets his client?

I can't. Lawyers can't take the initiative to deliver things to their clients. If they need related items, the detention center can inform their families. According to the regulations of the detention center, articles given to prisoners by their close relatives must be inspected by guards. Article 30 of the Regulations on Detention Centers stipulates that articles given to criminals by their close relatives must be inspected by guards. Article 31 of the Regulations on Detention Centers stipulates that a detention center may inspect the letters sent and received by criminals upon the entrustment of the case-handling organ. Anyone who is found to obstruct investigation, prosecution or trial may be detained and transferred to the case-handling organ for handling.
