What heartbreaking things have you heard or experienced?

The most heartbreaking story I've ever heard came from a speech by Ye Guangqin.

In the 1980s. Zeng Zhou went on an expedition to study giant pandas, fell off a cliff and died. So he was buried in Sanguan Temple. His classmates, all of them became very famous experts on giant pandas in the country. Lv Zhi, for example, and his teacher Pan Shiwen, for example, were leading them at that time. Zeng Zhou, a biology student at Peking University, stayed at Zi Sanguanmiao forever.

When his classmates left, they planted many, many plants unique to the Qinling Mountains around his tomb. Among them was the Taibai azalea. On the first anniversary of Zeng Zhou's death, his father came to Sanguanmiao from Shantou, Guangdong Province. The old man, a graduate of Tsinghua University, was alone at the time, and sat in front of Zeng Zhou's tomb, not saying a word, for a whole morning.

Sitting in front of Zeng Zhou's tomb, the old man took out a photo, it was completely a child, very spiritual gaze, green face. Looking out at the world. This old man only had this one son, and this son was admitted to Beijing University with the first place in Shantou, and he stayed in Sanguanmiao.

When the old man was leaving, he shouted to Dashan:

Zeng Zhou, dad is leaving, dad is old, he won't come to see you again.
