The red apples sent before Christmas are called Ping An Fruit. Because the eve of Christmas is called Christmas Eve.

"Ping An Fruit" is made up of imported apples with bright colors and good looks. Most of them are red snake fruits and green snake fruits. Of course, some domestic red Fuji apples are packaged as "Ping An Fruit". It is said that "safe fruit" symbolizes peace and harmony. The reason why "apple" is the first choice for "safe fruit" is to take the pronunciation of "apple".

The custom of giving Christmas fruits on Christmas Eve is unique in China. Because people in China pay more attention to homophonic, Christmas Day falls on December 25th, and Christmas Eve falls on the night of December 24th. The homonym of "apple" and "ping" of peace means that people in China have the auspicious meaning of "peace" of apples. Therefore, the custom of giving apples on Christmas Eve comes into being.

Christmas, also known as Christmas Day, is translated as "Christian Mass", a traditional western festival, which falls on December 25th every year. Mass is a liturgy of the church.

Christmas is a religious festival. Because it is celebrated as the birthday of Jesus, it is named "Christmas Day". Most Catholic churches will hold midnight mass on Christmas Eve on the 24th, that is, in the early morning of December 25th, while some Christian churches will hold good news and then celebrate Christmas on December 25th. Another branch of Christianity, the Orthodox Church, celebrates Christmas on January 7th every year.
