If the lawyer's practice certificate is revoked, he can't obtain the lawyer's practice qualification again in the future, that is, he can't engage in legal services as a lawyer. However, the law does not prohibit those who engage in legal services as ordinary citizens or corporate lawyers. But you can't engage in for-profit civil litigation agency services as an individual.
