legal analysis: an applicant shall not be issued a lawyer's practice license in any of the following circumstances: (1) he has no capacity for civil conduct or has limited capacity for civil conduct; (2) Having received criminal punishment, except for negligent crimes; (3) Being expelled from public office or having his lawyer's practice certificate revoked. A lawyer whose practice certificate has been revoked can no longer re-qualify as a lawyer, that is, he can no longer engage in legal services as a lawyer. However, the law does not prohibit legal services as ordinary citizens or corporate lawyers. But you can't engage in profit-making litigation agency services as a citizen.
