Taiwan's long drama "Unforgettable", which set a record for the longest number of dramas imported by CCTV, has a total of 526 episodes, and the first 168 episodes have been introduced by CCTV. Wang Wei, the director of the show, said, "I watch the broadcast of the show with the producer every night, and adjust the plot at any time according to the ratings, and adjust the plot direction in a mobile way, in order to create high ratings." However, Li Ming, vice chairman of the China Television Artists Association, said that this "shooting and broadcasting" model is difficult to promote in the mainland, "Korean TV generally broadcasts TV dramas 5 days a week, one episode a day, but the TV series broadcast every day is different, generally 5 TV dramas are broadcast at the same time, due to the long broadcast cycle, so Korean counterparts have enough time to arrange the following story according to the ratings and audience reactions."
