Can I use one ticket, or buy ticket for multiple days for the Yellow Mountain?

Hi, I am staying there for 3 days, and would like to know if I can visit mountain each day with a single ticket (hotel is several km from the entrance to the mountain)? To quote: "If you want to exit after the first day's visit and reenter on the next day, you need to register and get a proof at the ticket office before leaving."
Or, can I buy ticket valid for three days, that is cheaper than the 3 single entry tickets?

Thank you,
Vladimir
