144 eligibity

I am South Korean. My trip details is Incheon (SK) - Beijing Capital Int't (China, 6 hours) - Brussels (Belgium, 5 hours) - Accra (Ghana). I don't need visa to stay in Europe for less than 3 months, I have a visa for Ghana. Since i enter Beijing (B), from Incheon (A), and exit to Brussels (C), do i qualify to use the 144 hour free transit ? Does the follow up flight to Accra have any influence on my eligibility ?
