A Chinese doctor who saved a woman in San Diego has been praised by Internet users and also dubbed "a model Chinese tourist".

Tang Ziren, an emergency doctor from Beijing Chaoyang Hospital, said on his micro blog that he was visiting the SeaWorld adventure park in the California city when a tourist from the United States fell to the ground about 10 meters away.

Tang said he gave the woman cardiopulmonary resuscitation for more than 10 minutes until she recovered with the help of a defibrillator. The woman's identity was not known.
