Sunon Holiday hotel is located near Exit A of laojie Station of Shenzhen Subway Line 1(https://www.travelchinaguide.com/cityguides/guangdong/shenzhen/subway/line1.htm), and you may take Subway Line 1 from Laojie to OCT East directly. I think there is English map in the park, please don't worry.

what's the name of the OCT East stasion?? i've seen the shenzhen metro system map and there's no OCT East station. so, maybe it's written in chinese word. thanks for your help.
