It is true that the information of this training center can't be found on the Internet, but the training institutions authorized by the American Heart Association in China are relatively small at present, and it may be normal for some institutions not to find information. However, judging from the name of this institution, it is likely to belong to a private institution, and individuals usually recommend training in training centers affiliated to medical institutions. You can also log on to official website, a major local hospital, to find out whether you are authorized by the American Heart Association and whether BLS or HS training is available.
