1, time and energy input: the schedule of stars is very tight, including shooting, practice and performance. Live broadcast takes a lot of time and energy, such as product preparation, publicity and interaction. Stars don't have enough time and energy for live broadcast because they already have other projects and responsibilities.

2. Risk and pressure: Live broadcast is a real-time interactive sales method, which requires stars to sell and communicate in front of the camera. This will bring extra risks and pressures to the stars, such as the need to respond quickly to the audience's questions and deal with after-sales service. Stars don't want to add extra risk and pressure because of live broadcast of goods-carrying activities.
