My son was a premature birth, I gave birth to him when he was less than 28weeks old, he had many problems from his lungs to his heart. Luckily, we found Dr. Chow at that time to take care of my son, and gave him treatments. Now my son is already 12 years old, and his cardiopulmonary functions are pretty healthy, we see Dr. Chow as our friend, thank you Dr. Chow!
