Every holiday, people will miss their distant relatives. () What is the reason why the poet feels this way?

The living space of the ancients was very small, and once they went far away, it must be difficult to calculate the date of their return.

In ancient China, a typical agricultural country, people were busy with their work all year round. Solar terms (some of which later became festivals) became one of the rhythm standards for people to calculate agricultural harvest, and it was also a day when people generally agreed to have a "holiday". Rest at home and family reunion are undoubtedly the fastest days of joy and happiness.

Later, some large-scale festivals, such as Tomb-Sweeping Day, Dragon Boat Festival, Mid-Autumn Festival and Spring Festival, were basically based on seasons. Every holiday is naturally the calculation of the date of return, and it is also the unconscious memory of the family.
