China's protests against Covid restrictions which erupted over the weekend appear to have died down, as authorities begin clamping down.
A heavy police presence has been reported in several cities, and some gatherings were quelled or failed to materialise.
Reports have emerged of people being questioned and their phones searched.
But overseas Chinese have continued protesting, in at least a dozen cities across the world.
Last weekend's demonstrations had grown after a fire in a high-rise block in Urumqi, western China, killed 10 people on Thursday.
It is widely believed residents could not escape the blaze because of Covid restrictions, but local authorities have disputed this.
As a result, thousands took to the streets for days, demanding an end to Covid lockdowns - with some even making rare calls for President Xi Jinping to stand down.
But on Monday, planned protests in Beijing did not happen after officers surrounded the assembly point. In Shanghai, large barriers were erected along the main protest route and police made several arrests.
On Tuesday morning, police could be seen in both cities patrolling areas where some groups on the Telegram social media app had suggested people should gather again.
A small protest in the southern city of Hangzhou on Monday night was also quickly stopped with people swiftly arrested, according to social media footage verified by the BBC.
But in Hong Kong, dozens of protesters gathered in the centre of the city and at the campus of the Chinese University of Hong Kong, in a show of solidarity with demonstrators in mainland China.
Many also gathered outside Chinese embassies in major cities around the world like London, Paris and Tokyo, and universities in the US and Europe.
One expert suggested that local protests were not likely to die down any time soon, saying they were likely to "ebb and flow" because people were "not being called out to the streets in a controlled fashion... they move between social media and the street".
But Drew Thompson, a visiting senior research fellow at the National University of Singapore, added that it was also important to note that Chinese police had "tremendous capacity... [and] the ability of China to control these protests going forward... is quite high".
