On the fourth day of the Lunar New Year, we eat bamboo baskets.
If it is the fourth day of the Lunar New Year, you will basically eat Zheluo, which is a hodgepodge of leftover meals from the first to the third day of the Lunar New Year. It is commonly known as Zheluo among the people. If it is in daily life, the fourth day of the Lunar New Year is just an ordinary day and has no meaning of page number, so the meals can be daily.
The fourth day of the Lunar New Year is the fourth day of the first lunar month, also known as Sheep Day. It is a day for Chinese people to welcome gods. According to the old imperial calendar, the "three sheep (yang) kaitai" is often said to be a symbol of auspiciousness, and it is also a day to welcome the Kitchen God back to the people. On the fourth day of the Lunar New Year, the whole family eats Zheluo together. The so-called Zheluo is a hodgepodge of leftover meals from several days. They clean the New Year's goods, clean the room, and collect the garbage in one place. This is also a Chinese folk custom. It's said to be "throwing away the poor".
