The slogan of the Heaven and Earth Society is "Mom and Dad, set things right and see the light again", but when you meet an unidentified person, first turn these eight words upside down. If you are brothers in society, you will recognize each other. If you are an outsider, the other party doesn't know what to say, and your identity will not be exposed. Seventeen or eighteen people outside the village and on the roof shouted in unison: "The earth shakes Gorkon, and the mountains and rivers are beautiful throughout the ages." Everyone in the hall shouted: "The gate is close to the sea, and the three rivers have flowed together for thousands of years."
In the Duke of Lushan, the existence of the Heaven and Earth Society is anti-Qing and regaining sight. Moreover, there are indeed heaven and earth meetings in history. But many people don't know. According to historical records, the members of the Heaven-Earth Society are mostly farmers, small traders, vagrants in rivers and lakes, and working people at the bottom of society. The existence of heaven and earth society was often suppressed by the Qing government.
Members communicate in secret language, and even internal documents are implicitly called "shirts" or "gold is not exchanged". This also makes it difficult for future generations to understand this mysterious organization that has existed for hundreds of years.
