Will Zhu Hua textbooks expire?

Yes According to Zhu Ye's inquiry. The service life of educational materials in Zhu Hua is five years, because the value of the data will gradually decrease with the passage of time, and the accuracy and completeness of the data will be greatly reduced after five years. Therefore, the service life of educational materials in Zhu Hua is set at five years, which can ensure the timeliness and accuracy of data and avoid the influence of outdated or inaccurate data on decision-making.
