Yun Xiangxiang's back-to-back giveaway made the Clouds happy. Even if they didn't win, they were still delighted that Yun Xiangxiang thought of them at all times.
The fans of other actors envied the Clouds. Since this was the precedent set by Yun Xiangxiang, the other actors couldn't imitate it.
Even if they weren't worried about being called a copycat, they had to have some good gifts for the giveaway. But they couldn't buy it using their own money either.
If they didn't buy any products, they wouldn't have anything to give, since they had no endorsements concerning luxury brands. If they gave away everyday items, they would be called cheapskates.
Yun Xiangxiang didn't care what anyone else thought. She did this because she couldn't finish all of the products, and she wanted to promote the brand she was endorsing.
