is that correct? the grammar and others

Programming is very various, since they not only make active sports program, but also make inactive program.
=> There are various types of programming, including active sports program, inactive program, etc.
(Sorry that I don't know the programming names. But I guess you are meaning different types of programming.)

Other than correcting the grammar, I have "re-phase" some of your sentence.

(Programmes have many) various, since they (are) not only (making) active sports program, but also (making) inactive program. For instance, there (have) Oil Painting, 3D Sculpture, Craft, (etc.) Children (are) involve and enjoy them. Some (interesting classes) are from elmentary to intermediate level, so (they are) enable to suit (for) many people. In Chinese (Restaurant), there are many packages for them (to choose), (and) different (seasons have) different packages for them.

There're quite a lot of grammatic mistakes and your meanings are not clear enough. Why don't you type in Chinese and tell us your target readers? These will make us easier to translate the text for you.

Programming is very various, since they { are } not only { making } active sports program, but also { making } inactive program. For instance, there are Oil Painting Course { , } 3D Sculpture and Craft. Children { can also } involve and enjoy them. Some interest Classes are from elementary to intermediate level, so it is enable to suit { too } many people. In Chinese restaurant{s}, there are many packages for them { to choose }. Different season{s} { have } different packages for them.
