How to distinguish between block race and park race in extreme sports?

Extreme sports competitions can be divided into park competitions and VERT competitions. PARK is a venue with a platform or other equipment of various shapes for players to perform in a certain size range. U-shaped board is a U-shaped semi-tubular device for players to compete. The international standards and specifications for extreme sports venues classify sports venues into A-level, standard-level, B-level and C-level, which meet the international competition standards and can host international competitions.

Skateboarding jam competition is a competition in which several contestants compete on the court at the same time.

The ranking standard is the difficulty of their movements, but the success rate is the standard.
