Excuse me, what is the order of filming? By the script? Or by location?

It should be the most convenient and quick way to shoot. The director will make overall arrangements and prepare the most reasonable plan, generally not in the script order. For example, in a recent film made by Li Bingbing and Vic Zhou, when they first met, they filmed a sex scene behind them. The director will try to shoot all the scenes that need to be shot in the same place at once. For example, there are many shots of Pan Jinlian taking a bath in Water Margin, but the director will not shoot every episode bit by bit, but shoot all the shots needed for several episodes at once and then edit them for later use. In some scenes that need to go abroad, the time savings will be doubled. It is impossible to go abroad many times and shoot well at once. For example, if you see another dream, you will shoot all the foreign plays and then go back to China to shoot something else. Some people need special weather, and it is not easy to artificially create snow scenes or rain, so they will wait for that kind of weather to come and take pictures quickly, but this kind of situation is rare, and usually they will make the necessary scenery.
