This structure is known as the Bridge of the Three Armies, an ingenious engineering concept historically attributed to Zhuge Liang, one of ancient China’s most famous strategists.
The design is remarkably simple: three long wooden beams interlocked together, supported at just three points along cliffs or steep slopes. When assembled, the beams form a strong triangular structure capable of distributing weight efficiently.
According to historical accounts, this bridge was strong enough to allow thousands of soldiers and horses to cross safely—an impressive example of how ancient engineering relied on geometry rather than materials alone.
