Later, Sun Yat-sen chose a courtesy name (字), which was Zàizhī (載之) meaning "conveying it", based on the Chinese philosophical saying "literature as a vehicle to convey the "Tao"" (文以載道, "wén yǐ zài dào"). Courtesy names in China often tried to bear a connection with the personal name of the person. His courtesy name, however, was apparently seldom used, and is rarely known in the Chinese world. He has been referred to with the surname Chen as Chen Zaizhi (陳載之).
