Now, Wei, Zheng Daozhao and Gwangju, the secretariat and calligrapher, praised the merits of their father's life and expressed their good feelings for the motherland. During his tenure, he traveled to Yunfeng Mountain and wrote many cliff carvings carefully carved by stone carvers on impulse, which became the most popular one in the Northern Dynasties and was highly valued by future generations.
It is no accident that Zheng Wengong Beiting Yunfeng Stone Carvings can be passed down to later generations and traveled across the ocean.
During his calligraphy career, Zheng Daozhao realized that a relatively successful cliff stone carving is not limited to gorgeous words, superb calligraphy skills, and the quality of stone carving is also very important. It is one of the key conditions for "publishing stone to become famous and increasing day by day". Stone carving has different faces, among which carving skills play a certain role, but the key is the quality of stone. So "the stone is good, so it is published here."
The stone carving is integrated with the surrounding natural scenery, which is a major feature of Yunfeng stone carving. With the change of climate all the year round, even the best stone can't stand the natural erosion of time.
Because if it suddenly rains cold in the dog days, it will clear up again, and if it is exposed to the hot sun in the south, the surface of the stone carving will be suddenly eroded due to thermal expansion and contraction, leading to deepening weathering, which is particularly harmful.
However, Zheng Daozhao had long expected this, so in the choice of stone carvings, he not only considered natural weathering, but also took reasonable measures to reduce it. For example, the stone carvings of Yunfeng Mountain are mostly in the shadow of Yunfeng Mountain, and the stone faces in the east or west direction are mostly hidden in the quiet valley of trees. The dense trees block the erosion of wind and sand and the irradiation of strong light in the south.
