The Year of the Rooster has officially begun in China, marking the country's most important annual holiday.
The event is traditionally celebrated with fireworks, but several cities have limited the use of fireworks on safety grounds, as well as to avoid an increase in chronic air pollution.
Stalls selling fireworks in the capital were notably fewer in number compared to previous years.
In Shanghai and many other cities firecrackers and rockets have been completely banned.
In Beijing, members of the government were asked not to use fireworks in order to set a good example.
Each year the use of fireworks is responsible for hundreds of injuries and several deaths in China, aside from contributing to poor air quality.
The Year of the Rooster, which began at midnight Friday night local time (1600 GMT), follows the Year of the Monkey in the Chinese zodiac. It is connected this year with the element of fire, a combination that only exists every 60 years.
In years of the Fire Rooster, fortune-tellers predict notable scientific developments. Generally, the Fire Rooster is a symbol for optimism, innovation and progress.
In one of the world's biggest human migrations, hundreds of millions of Chinese head back to their family homes during the holiday.
Special trains and additional flights are planned in advance to help transport millions of travellers per day during the 40-day main travel season.
Factories and offices are shut for a whole week.
