Events are being held across China to mark the fifth day of the Lunar New Year -- or "Po Wu" as it's known in Chinese.

Traditionally celebrations start on New Year's eve, and go on until the fifth day of the lunar calendar's first month. A big part of " Po Wu" is getting up early to clean houses and also to eat dumplings. Some are filled with nuts or candies, and it's believed whoever eats them will have good fortune for the year. It's also the birthday of the Chinese god of wealth, so businesspeople usually go back to work and let off fireworks to ensure prosperity.

"Po Wu" is extra special this year as it marks a celestial phenomenon -- Jupiter and the moon have now moved to the same longitude creating the shortest distance between the two planets.
