Are all lawyers in five laws in Jiangsu specialized in handling criminal cases?

There must be. In criminal cases, I suggest you find a lawyer as soon as possible, and try to find a local lawyer in the court, procuratorate and detention center. Because criminal cases need personal connections, it is difficult for lawyers from other places. If it is a detention center, there are usually scalpers nearby who pull business under the banner of legal consulting companies. In fact, they don't have any qualifications. These fees are usually 1000, and then you get 500 for the lawyer you meet. Therefore, it is not cost-effective to find such a scalper.
