He has to personally check each clay sculpture after he has finished it, and will not hesitate to destroy and re-sculpt the sculpture if he is not satisfied with it. His strictness ensures the quality of his works. It is reported that under natural conditions, every clay sculpture here can be preserved for thirty to fifty years.
