There is a special custom to celebrate the Spring Festival in Hebei. Many people will specially make the dough into hedgehogs, and put some gold ingots on the hedgehogs at the same time, and put them on the door shaft at home on the 23rd of the twelfth lunar month, and take them off at the end of the month. This actually means getting rich, so hedgehogs have always been a symbol of good luck among the people.
Of course, in reality, hedgehog is really a lovely animal. Although it has thorns, if it is relaxed, the thorns are soft and will not prick people. Hedgehogs, like many animals, can predict natural disasters in advance. If a natural disaster is about to occur, hedgehogs may be different from peacetime, or show a strange quiet state, which is abnormal.
