在曾祖父出使日本前,曹氏宗族专门召开了宗族会议,族长专门嘱咐我祖父曹廷柱,千万不可将宣纸制造之秘诀泄露给外人。我祖父那时在族内也是长老,曹氏宗祠八把交椅就有他一把,他当然也明白这个道理。祖父前后几次赴日本做宣纸抄纸表演,把日本人看得眼睛都直了。 Prior to his great-grandfather’s expedition to Japan, the clan clan held a clan meeting exclusively and the patriarch specifically asked my grandfather Cao Tingzhu not to disclose the secrets of the manufacture of rice paper to outsiders. At that time, my grandfather was also an elder in the clan, and there was one of eight chairs in his clan Ancestral Hall. Of course he understood this truth. Several times before and after my grandfather went to Japan to do a paper-making demonstration of Xuan Paper, the Japanese people saw their eyes straight.
