Famous allusions of ancient children looking for relatives.

Before Pan Wu was born, Pan's father left home to do business, and Pan's mother spun and woven at home to support the family. There is no news of Pan's father, and his life and death are uncertain. Pan Wu inspired him to find his father.

At the age of 30, Pan Wu went out to find his father, running around day and night, and his feet never stopped. When the expenses on the way ran out, he used fortune-telling to solve his accommodation needs. Ten years later, he traveled all over eight provinces, finally found Pan Fu and returned to his hometown. On the way, his father died, and with the help of others, he had to carry the coffin back to China.
