Background: I am considering buying a comprehensive physical examination package for my parents, and I came across the package offered by the Henan Provincial People's Hospital Physical Examination Center. The price is quite steep, ranging from 3,000 to 4,000 yuan. I am looking for a self-financed option.

Location: Zhengzhou, Henan Province, China

Age: Almost 60 years old

Requirements:
1. Is it suitable to buy a comprehensive physical examination package? Can I get individual project diagnoses separately?
2. Are there other suitable channels, price-affordable options available?
