It is worth seeing the miracle of ancient Chinese engineering architecture. Looking around the upstream and downstream of the bridge, it is very shocking. With ingenious conception, exquisite material selection and exquisite workmanship, it is impossible for the construction of tofu residue project to be built on the basis of the construction experience after 1400 years.
