Thanks for everybody's concern. Below is the reply to your questions:
1) "Lali Warehouse Limited" do have Valid "Business Registration".
2) Land use is "Recreactional Type" allowing "Remote Control Race Track" on the list.
3) Plus 10M "Property/Public Liability" and "Third Party" Insurance coverage.
I support and praise the drive of the boss of warehouse to promote the off-road RC in HK.
Hope that other Ching could also support him to run this unique, beautiful race course of HK
