7 pax entry tickets to Juyongguan Great Wall for MAY 05, 2025

Hello,
I would like to buy 7 tickets to Juyongguan GW Section for the date of 5 May, 2025. It is 6 pax over 60 and one pax less than 60. I am confused about the price. You inform that people over 60 can visit the place for FREE but some web sites inform of reduced price to 50% of normal price. We will have a transportation and just want to buy entrance tickets. Thanks for reply.
