Millions of anti-government protesters have taken to Hong Kong's streets for more than three months, plunging the Chinese-ruled city into its biggest crisis in decades and posing a direct challenge to its political masters in Beijing.

Hong Kong cleaned up on Monday and train services in the city resumed, after another weekend of sometimes violent protests that saw pro-democracy activists vandalise a railway station and a shopping mall.

Nearly 50 people were arrested in the weekend clashes, police said, bringing the total number of arrested in the protests since June to 1,556.

The Chinese-rule territory is on edge ahead of the 70th anniversary of the founding of the People's Republic on October 1, with authorities eager to avoid scenes that could embarrass the central government in Beijing.

September 28 - The fifth anniversary of the "Umbrella" pro-democracy protests in 2014 that occupied parts of the city for 79 days.

Activists are expected to mark the anniversary with a rally.

October 1 - The 70th anniversary of the founding of the People's Republic of China.

Protesters are expected to rally in Hong Kong dressed in black, and authorities are likely to roll out a large security blanket as the Hong Kong government holds a low-key ceremony.

In Beijing, President Xi Jinping will oversee a massive military parade through central Beijing.

The Communist Party will be hoping the world see images of orderly troop formations and dancing civilians, rather than protests in Hong Kong.
