this is taken from a reddit user who describes what Sisters who make waves is:
For those who are unfamiliar with the show: Sisters Who Make Waves (乘风破浪的姐姐) is marketed as sort of "challenging" the limitations of ageism in the entertainment industry. Contestants are not just singers but also actresses and TV show hosts, all aged 30 and above. Those in their 40s and 50s have made it into the debuting group in the past two seasons.
The first season in 2020 made huge waves (heh) and went viral in China, and the debuting team included Miss A's Jia. Because of how popular the show was, the second season (2021) had a significant number of very famous China/HK/Taiwan celebrities such as Cecilia Cheung who didn't make the final group, and the ones who did include Na Ying, Rainie Yang, Bibi Zhou and Joey Yung.
Also because it was so popular, the same company made a male version called Call Me By Fire (披荆斩棘的哥哥) but they formed a 17-member group. Royal Pirates' James Lee joined this one but didn't make the group. One guy who did make it is a Korean-American called Nathan Lee (Lee Seung Hyun/李承铉) who used to be in Korean group TAKE.
A rival company similarly produced one called Shine! Super Brothers (追光吧！哥哥) for male celebrities who have debuted before. Yuqi is one of the show's hosts, and Nichkhun joined the second season of this one.
