Mumbai - Beijing and 4 days later Beijing - San Francisco

I am confused about my situation since I am flying from Mumbai to Beijing and Beijing to San Francisco with Beijing being the transit city.

I have confirmed tickets from Mumbai - Beijing and 4 days later Beijing - San Francisco based on the rules mentioned on this website.

Can you please confirm that I qualify for the 144 hr transit based on my situation?

I am concerned as I am traveling with my family and your help in this matter is greatly appreciated.
