As far as I know, there seems to be no limit to the age of the reference person in the first aid skill test that non-professionals can take. Therefore, it should be said that even minors can still take the certificate, but it is best to ask the relevant responsible institutions in your place.

However, there is no separate certificate of cardiopulmonary resuscitation (CPR). Generally, it is a certificate of primary emergency personnel, which is issued by the Red Cross to primary emergency personnel who have participated in the training of primary emergency personnel and passed the examination.

If you need this certificate, you must attend the primary first aid training of the local Red Cross. You can contact the local Red Cross for relevant information.

In addition, the training of primary emergency personnel usually includes four basic techniques (hemostasis, dressing, fixation and treatment) of cardiopulmonary resuscitation and trauma first aid.

If the emergency center in your area has affiliated training institutions (such as the emergency center in Shenzhen), you can also contact them.

The answer is for reference only.
