Both were given curfews between 11pm and 7am and banned from entering the Admiralty area.
The pair are accused of taking part and inciting others to join an unauthorised assembly, while Wong is further charged with organising the illegal protest.
The group’s Ivan Lam also appeared on the charge sheet, although he was not in court and was believed to have left Hong Kong on August 28.
The prosecution said it wasn’t sure that Lam was aware he faced an incitement charge and he would be brought to court as soon as he returns to the SAR.
The magistrate granted Wong and Chow bail on HK$10,000 and the case was adjourned until November 8.
They were told to report to a police station twice a week, and cannot leave Hong Kong, apart from trips they already have planned for next month.
The pair were caught up in a series of arrests by the police over the past two days, with former Hong Kong University student leader Althea Suen, lawmaker Cheng Chung-tai, and Chan Ho-tin from the now banned Hong Kong National Party also among those taken into custody over the ongoing anti-government protests.
Speaking after his release, Wong said the arrests would not deter protesters.
“We shall not surrender and I urge the international community to send a clear message to President Xi that sending troops or using the emergency ordinance is not the way out. We will continue our fight no matter how they arrest or prosecute us.”
