There are schools specializing in game design in France, and Montpellier is the third best public university. The better private design school is MJM School of Design in Paris. I'm an art major. If you are interested in design and production, you may learn more practical knowledge and be more market-oriented.

Considering that your major in China is French, your language ability is no problem, but it will be more difficult to apply directly because you have changed your major. Unless you can provide a very complete work.

I hope my answer is helpful to you!
