Break the pattern of division of labor between the main attack and the auxiliary attack machinery, cover each other and make breakthroughs, thus strengthening the all-round attack capability, enriching the tactical content and adapting to various complex situations.

Combined with the front attack cover, attack from the back deep area, forming a variety of supporting three-dimensional tactics, in order to break through the opponent's tight blockade. Pay attention to the cooperation between individual tactics and collective tactics, such as using double-line differentiation (straight spike or oblique spike), flat back area, changing hands and wrists, batter out of bounds and high-point drop, etc., to strengthen breakthrough ability.
