Introduction to the simulated ancestral house: The ancestral house where Sun Yat-sen was born is located on the north side of the front yard of Sun Yat-sen's former residence. After 1913, the Sun family demolished it. This is the family environment before and after the birth of Sun Yat-sen, which was restored and decorated using the house of a family named Lu. Many of Sun Yat-sen's later thoughts were inspired by the difficult farm life in his hometown in his early years.
