The recording of "Sister Lang" was launched two days ago, and there are rumors on the Internet that Qi Wei will participate in it. However, due to Qi Wei's overseas participation in Fashion Week, coupled with the continuous denials of her fans, the news was denied. Surprisingly, just after the fans just refuted the rumors, Qi Wei quickly returned to China to join "Sister Lang". It turned out that the program team was suddenly unable to participate in the original guests, so they urgently summoned Qi Wei to return to China to save the scene. This move caused dissatisfaction among some netizens and passers-by, who thought that the program team could have chosen Cao Lu as a replacement, but chose to recall Qi Wei from abroad, and it seemed that Qi Wei had robbed Cao Lu of the opportunity.
However, Qi Wei and Cao Lu do not have the same status in the entertainment industry, and the program team did not consider Cao Lu when looking for replacement guests. Therefore, Qi Wei's claim that she snatched Cao Lu's place is not valid. There are many reasons why the program team did not choose Cao Lu, including her relatively low popularity and lack of hype topics. The most important thing is that Mango Channel had invited Cao Lu to participate in "Sister Lang" before, but Cao Lu rejected Mango Channel because of participating in other programs, and Mango Channel had a bad idea about it, so it deliberately avoided Cao Lu. In addition, Cao Lu's topicality is not enough to attract the attention of Mango Channel, and her participation may only make the topic of the show last for a year, while Mango Channel is obviously more inclined to choose topics that can bring a longer tail effect. Therefore, Cao Lu's non-participation itself provides a discussion point for the show that will last for many years.
