Why is it that some elderly folk have "hearts of innocence."

Every person’s life was changed in July of 1937.

During the Second Sino-Japanese War between China and Japan in 1937, three of China's universities merged to form the National Southwestern Associated University.

On May 4, 1938, the Southwest Associated University officially opened. It was a truly historic moment.

After the establishment of New China in 1949, many graduates of the Southwestern Associated University studied abroad but then returned to support their home country.

The stories of the people are national treasures.
