HONG KONG — A day of demonstrations across Hong Kong on Saturday began with a peaceful teachers’ march and ended with standoffs between the police and young protesters. But after a week in which both sides were criticized for taking violence and mayhem to new levels, there were no clashes.

In the densely populated Mong Kok district, protesters gathered Saturday evening outside a police station and shined laser pointers at windows and threw eggs at the officers guarding the entrance. Officers in riot gear took over nearby streets and chased some demonstrators. But the crowds had largely dispersed by 8 p.m.

Some supporters of the protest movement may have been saving their energy for Sunday, when organizers are hoping for a large turnout in Victoria Park, in the Causeway Bay district. They had applied for a permit to march from the park to the Central district, essentially the same route taken in two enormous marches in June, but the police turned them down. Organizers have appealed that decision, saying that it puts people in danger because many are likely to march regardless.
