There is no requirement for culture, as long as you show super basketball talent. Generally, people who have made certain achievements in college leagues and performed well participate in the draft, but there are also high school students, such as James, the favored son of heaven, who received much media attention in high school and finally directly announced their participation in the NBA draft. The NBA draft is an annual activity to select new players for the NBA. In the draft, 30 NBA teams can choose young male players who want to join the NBA. The selected players are called NBA rookies. All American players can automatically enter the NBA draft after graduating from college, or they can announce their participation in the draft between high school graduation and college completion.

The NBA sets two dates every year, and all players who wish to participate in the draft must announce their participation before the first date. After that, the NBA will set up a training camp for these players to show their abilities and skills to the team.

The second date, that is, the final announcement to participate in the draft, is one week before the draft. Any player can make a decision before this, withdraw his name and not participate in the draft of that year. This date is very important for college players. If they don't officially announce their participation in the draft until they finally announce their participation in the draft, they will lose the opportunity to study in college whether or not an NBA team chooses them in the end.
