In the same arena, why is the gap between CBA and NBA so big?

First of all, it is obvious that the seating arrangement, the NBA audience is very close to the field, and it seems to be integrated with the stadium, while CBA clearly divides the venue and the audience:

First of all, advertising, surrounded by billboards, forms a wall between the venue and the audience. If you look closely, you can also find that the players of the team are sitting behind the billboards, directly separated from the venue, and there is a high step between the players' seats and the audience, putting the audience behind them;

Below the basketball stand is the press box, and behind the NBA press box is all the audience, but the back of this arena is so empty, why do you have to make an arc blank area? The audience behind the backboard is separated by this big blank.

Looking back at NBA players, they sat completely on the sidelines and there were no obstacles behind them.

In addition, the corner of the CBA stadium is completely empty, forming a huge black hole walkway, and the NBA stadium is also a channel for players to quit at that angle, but if you don't look carefully, you will feel where everyone is, and you have watched the live broadcast. When the player walks through this aisle, it is very small. As far as this Guangdong arena is concerned, the walkway is at least three times wider than the NBA, so it looks too empty.

After talking off the court and watching the stadium, where do you think the CBA stadium is the most fall in price? Yes, that's a basketball stand. I don't know if cba's basketball stand is good, but its perception is too low. It looks so thin, especially the color scheme of this super earth painting. Timer on the back panel. What is that? I have always felt that this square timer in cba is particularly unstable. When I watch cba games, when there is a dunk, I am really afraid that the swing range of the timer above will break and hit the players, and then it is still a matter of color matching. Green numbers are ugly. Who designed red with green?

One more thing about the basket, it sounds unstable! In a game I watched yesterday, one side threw a three-pointer and missed it, then hit the basket (while the iron was hot). The basket actually made a huge sound, which should be the sound of shaking back and forth because of loose screws! This kind of sound is also very destructive!

And the floor. I don't know what kind of floor CBA uses, but NBA seems to have strict requirements on the floor. As a layman, CBA's floor is poorly reflective.

When NBA broadcasts, you can often see the screen of the floor reflection technology platform, as well as the lights around the stadium screen and the central big screen, but I specially watched several cba venues, and basically I can't see these things, which may also be one of the problems that affect the visual perception.

Secondly, let's talk about our Wukesong Arena. You said that CBA doesn't have that much money to operate and maintain stadiums, so as an Olympic stadium, there will always be no money, right? First of all, when I look back on the 2008 Olympic Games, when China played against the United States, the United States often slipped in the Wukesong Stadium, and several guards of the United States were caught several times. I think it's the floor.
