The so-called dehydration data and dehydration heat refer to the real data and heat of online drama after the platform and Weibo officials exclude the heat and heat paid by themselves or deliberately brushed by fans. Generally speaking, an online drama with a good cast and a good plot may not get everyone's attention in the early stage, but in the later stage of this online drama, it is absolutely possible to enhance the broadcast volume and popularity by virtue of the plot and actor acting skills.
However, due to different platforms and different broadcast times, the ratings and dehydration data of a TV series or online drama will also be affected. If a good TV series is promoted by a broadcast platform, the dehydration data and dehydration heat of this online drama will rise linearly. Even the dehydration data and dehydration heat of some online dramas are not worse than the high-quality TV dramas broadcast by TV stations. This also shows that good TV dramas don't care about the broadcast platform, and their dehydration data and heat can show that the TV series has been successful.
To sum up, I think the dehydration data of online drama refers to the dehydration data and heat of this TV series or online drama after a platform removes the redundant broadcast volume or the repeated broadcast times of an ID.
