First of all, we must be familiar with the rules of the game, improve the theoretical level and master the theoretical rules, and then we can try the bull knife on the field.
The second is to master the refereeing skills and improve the level of adjudication.

The conversion of attack and defense in basketball games is carried out quickly, sometimes making it difficult for people to accurately judge, which requires the referee to actively move, seek the best angle, always pay attention to the position of all team members, in order to maintain the fluency of the game, the accuracy of the judgment, the referee should master certain skills when on the scene.
First of all, do a good job of division of labor, often maintain the gaze of the eye, under the premise of not violating the principle, do some "whistle", encourage work, give affirmation to an accurate judgment of the companion, will greatly enhance the self-confidence of the companion, the two cooperate well, in the referee will feel happy, otherwise it will be very awkward; both do not explain too much with the athlete coach, because due to different angles, the role is different, and the degree of understanding of the rules will have different views on some judgments, such as no special circumstances, After the game can leave the field; the third should be familiar with the work of the record desk, the record desk work itself is part of the basketball referee, in the scene with the record desk personnel to cooperate with the good or bad, will directly affect the on-site work, when the game time is over, while there is shooting, fouls, etc., the on-site referee do not rush to see the judgment, should first go to the record desk, learn about the information, determine whether the time comes first, or shoot first, the situation is clear, and then make a judgment.
In addition, the provisions of the rules should not be rigidly applied, and should be applied well under the premise of understanding. Sometimes almost the same action, occurring in different places, different moments, can be handled differently, these must rely on the usual continuous summary and the accumulation of on-the-spot experience, so as to improve their own level of refereeing.
In addition, we should practice more, learn more, and enrich the experience of the scene, we should develop the good habit of summing up in time after each scene, play it back in the mind like a movie, and summarize what we have gained, what problems there are, and which concepts are not clear. Especially in rare cases, even a little gain by summarizing is gratifying, and over time, over time, your ability to analyze and solve problems on the spot will be improved.
In addition to paying attention to practice, you must often watch the on-site work of your peers, especially the higher-level referees, and really learn the kung fu of others. Such as the decisiveness of the judgment, the flexibility and skill of handling, the specification of whistles and gestures, and the special emphasis here on gesture irregularities will directly affect the effect of refereeing. Because gestures are the referee's way of pronouncing judgments, the expression of voice, the explanation of penalties, must be done in accordance with the rules, but can not be self-created, through the normative gestures of the referee's determination, trade-offs and handling organic expression, so that the players, coaches, audience at a glance. Gestures, usually in the dead ball and stop the game clock to do, do not rush to do, may wish to slow down a little, and a slight pause, especially must be the number clear (if some of the number of large and primary school students of the game, but also appropriately combined with some spoken language) to stand at a distance of 6-8m from the recording table, the height of the gesture is level with the eyes, and to leave the body slightly.
There is also a need to learn some basketball techniques and tactics If possible, it is best to play basketball often and experience various actions, which will help the on-the-spot work. The referee knows the tactics in order to grasp the timing of the judgment in time. If the coach is replaced by a tall center, the referee should foresee that the team will strengthen the under-basket attack, so it should observe the actions of the players under the basket on both sides, and finally of course have professional ethics.
In short, as long as you love the referee's work, and carefully study and understand the rules, master the refereeing skills, practice more on the spot, humbly seek advice, and constantly summarize, you can be a good basketball referee.
