1. Look at the trademark: the original umbrella opens smoothly, while the imitation umbrella opens awkwardly. There are trademark imitation marks inside the original product.

2. Look at the trademark: the genuine umbrella cloth is matte and has good density, while the imitation cloth has a shiny surface and a thicker feel. The cloth surface is obviously different.

3. Texture: The imitation products have different fastnesses, are easily deformed and broken, and obviously do not have enough texture when used for the first time.
