我们必须赤胆忠心为人民。

We must serve the people with utter devotion.

高度忠诚(或：赤胆忠心咒如何起作用？)

High Fidelity or: How does the Fidelius Charm work?

如：红卫兵、根正苗红、又红又专、赤胆忠心干革命、红心永向红太阳等。

Such as: the Red Guards, root seedlings are red, both red and professional, and loyal to join the revolution, such as Red Wing to the red sun.

我们大概有二十个人，这就大大削弱了赤胆忠心咒的力量。

And as there are around twenty of us, that greatly dilutes the power of the Fidelius Charm.
