The Ching Ming Festival, which is also called the Qingming Festival or Tomb Sweeping Day, usually falls on the fourth or fifth day of April. It is an important occasion for Chinese people to show respect for their ancestors and departed family members. Remembering ancestors is also an act of filial piety, which is a valued tradition in Chinese culture.

A lot of people visit their ancestors' graves for tomb sweeping on the day of the Ching Ming Festival as it is a public holiday in Hong Kong. Before the visit, family members share the work and get things ready, such as buying incense sticks, flowers, paper offerings and food offerings. During the visit, people sweep the tombs and clean the surrounding areas. They burn incense sticks and paper offerings, such as paper money and clothes. They place flowers, especially chrysanthemum, in front of the gravestones to remember their ancestors. They also lay out food offerings, for example, a roasted suckling pig, a steamed chicken, fruit and wine. Then, they pray to their ancestors and ask for blessings. Finally, they may eat up the food after the traditional ritual.

The custom is simplified in some families. People simply clean the gravestones, put flowers in pots or vases, and bow to their ancestors to show respect for them.

At the time of the Ching Ming Festival, the weather is warm and favourable for outdoor activities. People may arrange an outing with their family members. They may go on a picnic, hiking or kite-flying to enjoy the beauty of nature.

In Chinese, "Ching" means "clearness" and "Ming" means "brightness". The origin of the name is related to the weather at the beginning of April, which gets warmer and brighter. People start to wear light clothes and walk outside to feel the vitality of life in spring.

Some Chinese people believe that burning incense sticks and paper offerings can transmit money and other goods to their beloved ancestors. It is a way for them to show their love for departed family members.

During the Ching Ming Festival, people honour their ancestors in different ways. Some people prepare a lot of things to worship their ancestors while some simply bring flowers to the graves and bow to their ancestors. Nevertheless, their love and respect for their departed family members is the same. Through tomb sweeping, people treasure the traditional Chinese values of remembering ancestors, filial piety and the importance of family ties.
