How many folding screens does Huawei have?

I know that Huawei has launched five folding screen phones. They are Huawei Mate X, Huawei Mate Xs, Huawei Mate X2, Huawei P50 Pocket and Huawei Mate Xs 2. These mobile phones all adopt folding screen design, which makes the mobile phone more convenient to carry in the folded state, and at the same time, it can provide more screen space in the unfolded state to meet the different needs of users.
