What does the regeneration protection of precious documents mean?

The so-called regeneration protection means making substitutes for precious documents, and using substitutes in the future to properly protect the original. Beijing Hanlong Industrial Co., Ltd. has been committed to the regeneration and protection of precious paper documents for 30 years, and adopted modern technologies such as miniaturization, digitization and analog copying, which not only effectively protected the original paper documents, but also promoted their dissemination and utilization.
