How many days will it take to put up reactionary slogans and enter the detention center?

If the circumstances are serious, is this a matter of staying in the detention center for a few days?

There was a real case: the father and son failed to overturn the "Tiean case" because of repeated petitions, but they found another way to attract the attention of the party and government leaders by publicly posting and writing reactionary slogans. At 1 am on April 28, 22, Yan Tousheng and his son posted more than 1 inflammatory slogans at the entrance of Dongshanba Village, the entrance of Chaling County Committee, the bazaar, Layuan Street and Changlingping. After being reported by the masses, at 12 noon that day, Yan Tousheng and his son were arrested by the police.

In p>22, Yan Tousheng and Yan Xi, from Chaling, Zhuzhou City, Hunan Province, were sentenced to three years and four years' imprisonment by Zhuzhou Intermediate People's Court and deprived of political rights for one year.
