Badminton doubles, weak partner, how to arrange tactics?

When your teammate serves, you are responsible for the backcourt ball, complete the smash and pick the high ball, and once your opponent hits the ball in front of the net, let him pick the ball to the backcourt. Based on your teammate's ball, when he receives the opponent's ball, let him pass it back to his (opponent's) server. Under normal circumstances, he will only consider that the opponent will return to the backcourt after serving, and often ignores the empty court that just served. When serving, you'd better serve a tall and long ball. Even if the opponent receives the ball, it usually only hits the ball to the frontcourt. The most important thing in doubles is that two people can't just stand on one point in the process of playing. If you stand in the left rear when you return the ball, your partner should wait for the ball to return to the right service line, and at the same time, you should take a quick step towards the money after you return the ball. Finally, ask your partner to strengthen the ball training. Playing badminton is not by brute force, but by skill. ) The above is my personal opinion.
