As for the question "There is a custom that you can't take things out in the moon house", the following is my answer:

This custom originated from the full moon ceremony in China traditional culture, also known as full moon wine. In China, the full moon is regarded as a symbol of a baby's healthy growth, so the family will hold a full moon ceremony to celebrate the arrival of the baby's full moon.

The full moon ceremony is usually held within one month after the baby is born. According to this custom, things in the house can't be taken out during the full moon ceremony to show respect and blessing to the baby. This is because the full moon ceremony is considered as an important family activity. Families hope that by keeping the things in the house motionless, it symbolizes the unity and stability of the family, and also implies that the baby's future life will be full of stability and happiness.

The way to celebrate the full moon ceremony varies from region to region and family, but it generally includes the following aspects: First, family members will invite relatives and friends to the full moon banquet to celebrate the arrival of the baby. A full moon banquet usually prepares a sumptuous banquet and various delicacies to express the family's blessing and joy to the baby. Secondly, the family will prepare a full moon cake for the baby, and a small candle will be inserted on it to symbolize the baby's birthday. The family will sing birthday songs around the cake, and then the baby's parents will help the baby blow out the candles, which means that the baby's first birthday wish will come true. Finally, the family will prepare some gifts for the baby, such as gold and silver jewelry, red envelopes, etc., to show their blessing and care for the baby.

There are some related allusions and extensions to the full moon ceremony. In the traditional culture of China, the full moon is regarded as an auspicious symbol, so the full moon ceremony is also regarded as an important auspicious ceremony. In addition, the full moon ceremony is also related to the traditional "Hundred Days Banquet". In China, the centenary of a baby's birth is considered as an important node, and families will hold centenary banquets to celebrate the baby's healthy growth. Full Moon Ceremony and Hundred Days Banquet are both ways for families to express their blessings and joy to their babies, and they are also important links in inheriting the traditional culture of China.

In short, the full moon ceremony is an important custom in the traditional culture of China. By celebrating the arrival of the baby's full moon, families express their blessings and joy to the baby. Things in the house can't be taken out to maintain the unity and stability of the family, which means that the baby's future life will be full of stability and happiness. The celebration of the full moon ceremony includes full moon banquet, full moon cake and gift giving, which is related to the traditional one-hundred-day banquet. These customs and celebrations are important parts of China's traditional culture, showing family unity and blessing to the baby.
