Visa free transit from PEK through HKG to Ho Chi Minh

Booked flight to china and vietnam for work, forgot to check my entry permit (stupid, expired a week ago...) rebooked my flights as i had 2 stop overs in PRC so understood that i couldn't get the 72 hour free transit.

just want to make sure this trip is fine. Travelling on a Dutch Passport from
Amsterdam - Peking (stay 50 hours) - Hong Kong (transit 3 hours) - Ho Chi Minh (3 days ; visa arranged) - Guangzhou (transit 4 hours) - Amsterdam.

thanks,
