Incoming travellers will no longer need to quarantine, marking a significant change in the country's Covid policy as it battles a surge in cases.

They will still require proof of a negative PCR test taken within 48 hours of travelling.

The move has been welcomed by many eager to reunite with family.

In the coming weeks, 400 000 people are expected to travel to mainland China from Hong Kong, with long lines for flights to cities such as Beijing and Xiamen.

Double-decker buses packed with passengers

On Sunday, double-decker buses packed with passengers arrived at the Hong Kong-Zhuhai-Macau Bridge to catch buses to Guangdong province, including college students returning home.

One man told the BBC he hadn't seen his extended family in three years and could not hold back his excitement, having just bought a ticket back to the mainland.

Hundreds of thousands of people are expected to travel to China in the coming weeks.

The country's reopening comes at the start of "Chunyun", the first period of Lunar New Year travel. Before the pandemic, it was the largest annual worldwide migration of people returning home to spend time with family.

Two billion trips are expected to be made this Lunar New Year, double the number that travelled last year.

Li Hua, who travelled from the UK to China - where her family lives - for the festival said it had been "too long" since she had returned, "I'm so happy to be back, and breathe Chinese air. So happy, so happy".

But there is concern from some that opening the borders will result in more transmission of Covid-19.

Some local bus drivers told the BBC they are worried they might get the virus from incoming travellers and want their companies to provide them with more protection.

World strictest Covid health policies

Over the past three years, China has had one of the world's strictest Covid health policies, which saw numerous lockdowns, frequent testing requirements and a significant impact on the nation's economy.

The government recently walked back that policy after mass protests across the country, triggered by a fire in a high-rise building in the Xinjiang region that killed 10 people. Many Chinese believed the long-running Covid restrictions contributed to the deaths, but authorities denied this.

Since China abandoned the key elements of its Covid zero policy, there have been reports of hospitals and crematoriums being overwhelmed, but the country has stopped publishing its case numbers and reported only two deaths on Saturday.

On the same day, the Chinese government banned over 1000 social media accounts critical of its handling of the virus.

The anticipated surge in cases and travel out of China has prompted many countries - including the UK - to impose requirements for a negative Covid-19 test on people arriving from China, drawing the ire of the Chinese government.
