FROM NANYANG AIRPORT TO DENGZHOU CITY THEN FROM DENGZHOU CITY TI XINYANG CITY

Dear Sir/Madam, I would like to go to 2cities one in Dengzhou while the other one in Xinyang. If I arrive Nanyang airport around 1615hrs, is there a bus service or train service operate from Nanyang airport to Dengzhou? If so, what is the one way estimated cost for a train or bus from Nanyang airport to Dengzhou?
I will stay Dengzhou for few days then from Dengzhou to Xinyang, is there any transportation by bus or train service to Xinyang? If so then what will be the estimated cost for one way?
Hear from you soon.
Thanks
Ricky Sung
