My former political science teacher.

Around 2012, he went all out and bought several properties in a few provincial capital cities.

Around 2015, he deactivated his social media accounts and stopped making public statements.

In 2018, he told us that history was about to undergo a major change.

In 2019, he sold his properties at their peak, keeping only two for his own use.

In 2022, he started buying gold with the money from selling his properties.

In the second half of 2022, he took a long leave, avoided infection, and did not get vaccinated.

In 2023, after retiring, he went to the United States to live with his daughter in her retirement.

From my observation, he has a very distinct characteristic: extreme calmness. He is good at analyzing problems from a structural perspective. He doesn't like to analyze issues from the angles of human nature, emotion, or value; instead, he prefers to analyze them from logic, patterns, and structure.

Moreover, he never argues with others in public. Only during class, when he encounters particularly trusted students, will he say some very insightful things. At other times, he appears dull and ordinary, as if he doesn't have any special insights.
