first month, Tai and Chan Kin-man resumed their teaching duties at their respective universities and OCLP handed over the command of its medic, marshal and supplies teams to the student groups, the Hong Kong Federation of Students and Scholarism. On 3 December 2014, the Occupy Central trio, along with 62 other key figures turned themselves in to the police, admitting taking part in an unauthorised assembly as originally planned. They declared that they did so to fulfil their promise to bear legal responsibility and uphold the rule of law, as well as to affirm their principles of love and peace.

Tai also worked on a "smart voters" system involving 25,000 voters who would indicate their preferences on an interactive poll and would be informed of the popularity of candidates according to polls the day before the official vote and which would be updated through exit polling two and a half
