A teacher's tale of revolutionary passion

Yao Yuzhen is often mistaken for a tourist guide because she's usually found wearing a wireless microphone and leading visitor groups at historic sites in Jinggangshan, Jiangxi province.

But in fact, she's a teacher of a very special group of students. They hail from across China, are of different ages, work in different fields and only receive a short period of training.

However, they all have one thing in common: They play a leading role in their departments, bureaus or high-level government departments.
