Why do top foreign singers rarely film and rarely cross borders?

Because top singers don't distract themselves from other things, because concentration will succeed. A person's energy is very limited, and it takes too much sweat and time to reach the top level in a field.

Only people with half a bucket of water will shoot an advertisement today and play a bad movie tomorrow. People must maintain this good level and never relax. If you don't work hard, someone new will take your place tomorrow. No one dares to leave his post to develop in other fields.

Although you have become famous, you will keep the admiration of your fans by pursuing perfection. If you neglect to practice, you will be easily crushed or even replaced by others. If you no longer have a position, crossing the line will only be laughed at. This truth is easy to understand. If you used to be in the clothing business, one day you will go shopping. Others must think that you can't make clothes, and the level can be imagined!

In China, the diversified development of music, film and television has become a normal state, and it is difficult to survive simply by singing for several years without releasing an album. Perhaps the different national conditions are the direct reasons for forcing artists to cross the border.
