Are There Any Words or Symbols Carved on the Bricks and Stones of the Great Wall

There are some bricks and stones on the Great Wall that bear words or symbols. Some of these inscriptions were made by the builders themselves. They might record the date of construction, the name of the work team, or a simple prayer for safety. In later years, soldiers stationed on the wall also left their marks. These could be messages to comrades, expressions of homesickness, or records of significant events. However, much of this carving has been damaged over time due to weathering and human activities. Nowadays, such inscriptions are protected as part of the cultural heritage. Archaeologists study them to gain insights into the history of the Great Wall's construction and the lives of those associated with it, while conservation efforts aim to preserve these precious traces of the past.
