Given that the show managed to air in 2023 despite having a K-actor, many assumed that the '"Hallyu Ban" is really over and that many more C-dramas starring Korean actors can finally air.
It is the third in the liar series of dramas following The Wife's Lies and The Lover's Lies which all starred Jia Qing as the leading lady.
It is part of the list of dramas that were affected by the Hallyu Ban, an unofficial ban that was in effect in China to restrict all forms of Hallyu aka Korean Wave due to the political disagreement between China and Korea over THAAD. On October 31, 2017, there were reports that both sides were making a move to mend diplomatic ties and news that the virtual ban has been lifted came days later.
It stars Korean actor Jung Il Woo which is why the drama hasn't been able to air.
