144-Hour Visa-Free Transit in Beijing

Hello We are an Argentine family of 5 members, parents and 3 children over 18 years of age. We process the visa for China in the embassy of our country. The requirements indicated to have the purchased ticket, so at the time of ordering the shift we had made the purchase, but before the time of the shift there was a change in the requirements, requesting a bank account with 3 months old and movements in it. . My youngest son, a 23-year-old student, did not comply with this requirement, although he has a bank account and did not have any movements, basically because he still depends financially on his parents and the visa was not granted.
We travel to Beijin from Bali (Indonesia), we are 5 days in Beijin and then we travel to Australia.
Could you please inform me if it is feasible for my son to enter with 144-Hour Visa-Free Transit in Beijing?

I await your response
Thank you very much
