Family and friends who visited Joshua Wong on the first day of his prison term on Friday said he seemed to be in good spirits, with a lawyer telling RTHK that the young activist is expected to be released as soon as December this year.
A human rights lawyer, Bond Ng, said that he had visited Wong and was told that the activist could be released as soon as December 17 upon good behaviour.
Ng also said that Wong will be filing an appeal against his jail term with the Court of Final Appeal.
Wong's mother and Demosisto party member Derek Lam were among those who visited him at the Pik Uk Correctional Institution – which houses prisoners aged below 21.
Lam quoted Wong as saying that he was trying to adapt to his new life, and that he wasn't feeling anxious or stressed. Lam also said his friend called on others to persevere.
Nathan Law, who was jailed for eight months, and Alex Chow, who's serving a seven month term, are temporarily being held at the Lai Chi Kok Reception Centre before being moved to other prisons.
Law's family and Occupy leader Lester Shum were among the people who visited the centre on Friday. Talking to the media, Law's mother voiced support for her son, describing his actions that led to his imprisonment as "selfless".
The Court of Appeal handed down prison terms for the three activists after the Department of Justice asked for a review of the original non-custodial sentences they were given for their roles in storming Civic Square just before the Occupy protests began in September 2014.
