Is it true that koi fish Dawang app changes mobile phones?

Looking at Tik Tok's advertisement, I found koi fish Dawang Software, saying that a certain number of gold coins can be exchanged for mobile phones. Finally, I collected all the gold coins, saying that I needed more than 40 activities, and I needed them when I collected them. Has been deceiving users to watch advertisements. There is no need for activities in the communication rules, which is obviously cheating.
