1, serve:
(1) When serving in a table tennis match, the server must throw the table tennis up almost vertically with his hands, and must not make the table tennis rotate, and make the table tennis rise not less than16cm after leaving the palm that does not clap hands, and the table tennis must not touch anything before falling down.
(2) When the table tennis drops from the highest thrown point, the server can hit the table tennis, so that the table tennis first touches his own table area, then crosses or bypasses the net device, and then touches the table area of the receiver. In doubles, the table tennis should touch the server and the receiver's right half area successively.
(3) From the beginning of serving to the time when the table tennis is hit, the table tennis should always be above the table and outside the end line of the server, and it should not be blocked by any part of the body or clothes of the server or his doubles partner.
2. Transposition:
The transposition in table tennis is that one side gets 1 1 first, and the other side must exchange directions. If the score is 5:1or 5: 3, after switching places, the starter becomes the receiver, the receiver becomes the server, the server becomes the receiver, and the other side receives the service.
