Ts'ai

Ts'ai Ch'ien 蔡乾 was born in 1908 in Changhua near Taichung, Taiwan (Formosa). His father was an accountant in a rice shop and a descendant of the three hundred Fukienese families who went to Taiwan with Koxinga, who led a rebellion there against the Manchus. At the age of six Ts'ai Ch'ien entered primary school, studied Japanese, and graduated after eight years. He taught at the same school, in Changhua, for one year.[…] In Shanghai Ts'ai studied sociology and learned something about Marxism.

Ts’ai Yüan-p’ei (also named Ho-ch’ing and Chieh-min) (1876-1940) was born in Shanyin County, Chekiang Province. He passed the second civil service examination in 1889 and the third in 1892 which secured for him the highest degree, han-lin.

The origins of what paper cognoscenti call “true paper,” which requires the breaking-down and reconstitution of plant fibers, are often dated to A.D. 105 and linked to Ts’ai Lun, a eunuch in the court of Emperor Han Ho Ti of China.
