I wonder if it is true that some film and television companies recruit actors and say free training?

Many of them cheat money and color. You'd better choose a regular school. The recruitment of Hengdian film and television should be true, at least in Hengdian, you can't cheat money blatantly, but the opportunities are not necessarily as much as they advertised. Some companies that recruit graphic models, such as letting you take a head-up photo in a studio, must have an agreement with the studio to make a profit, so taking a set of photos even costs more than 2,000 yuan, so I suggest you find a more professional school.
