The statement "history is solidified" may have different meanings from different perspectives:

First of all, history is composed of a series of past events and activities. and activities have elapsed in time and can no longer be changed or undone. Although these past events and activities are in the past, they have an impact on the present and future. This influence can be culture, values, social structures, or the behavior and decisions of individuals and groups. From this perspective, history is "frozen" because it is fixed and unchangeable.

Secondly, history also refers to the recording, research and interpretation of past events and activities. These records and research are usually written into text, images, audio and other materials, which become an important basis for us to understand the past, understand the present, and predict the future. Once these data are formed, they also have a certain degree of stability and will not be easily changed. From this perspective, history is also considered "frozen."

Finally, history also has educational value, allowing people to learn from the experiences of their predecessors and avoid making the same mistakes again. This educational function also makes history "solidified" to a certain extent, because its educational and enlightening functions will not change over time.

To sum up, the statement "history is solidified" can be understood from different angles as: history is fixed, stable, and educational.
