By the way, when to use a reflective umbrella and when to use a soft umbrella.

Soft umbrellas can get softer and more divergent light.

Reflective umbrella can get sharper and more concentrated light.

The light quality of reflective umbrella is a little harder than that of soft umbrella, and it is easier to form shadows. Also, the light of a reflective umbrella will be narrower than that of a soft umbrella of the same size.

In Japan, many photographers favor the application of umbrellas, because it is small and easy to store and carry, which may be related to the actual situation of Japanese people.

In my opinion, when you want to create a three-dimensional effect, you can choose a reflective umbrella because its light is tough, such as texture, space, sidelight, backlight, luminescence and so on.

When you want to create a soft light, warm feeling, or even a picture, you can choose a soft umbrella.

Of course, this is not static. You need to understand their respective characteristics and then apply them to corresponding situations. Some rules are doomed to be broken. You said when to use a reflective umbrella and when to use a soft umbrella. In fact, this is a bit upside down in method.
