One, field: It is the solid plane of a rectangle, trouble-free content. To the formal competition with international basket main couplet, the measure of field wants from borderline inside rise along the quantity. To all other match, the relevant section of international basket couplet, approval having right accords with the existing field inside following size scope: Length reduces 4 meters, width reduces 2 meters, want its to change only become scale each other.
