对中国广西、贵州、云南以及越南北部等地区的传统手抄本进行了广泛调查。调查包括了上述地区内的42个地点。所涉及的手抄本主要是上述地区中的方块壮字或中国贵州布依、云南东部的侬、沙以及越南北部地区的侬和岱等文字的抄本。通过调查,发现在上述地区使用的很多常用方块字有相当广泛的区域性,同时有小区域创新的痕迹。 Extensive investigations of traditional manuscripts in Guangxi, Guizhou, Yunnan and northern Vietnam were conducted. The survey included 42 locations in the above areas. The manuscripts in question are mainly copycat letters in the above-mentioned areas or the texts of Nong and Dai in the areas of Bouyei, Guizhou, China, Lennon and Sand in eastern Yunnan, and northern Vietnam. Through the survey, we found that many of the commonly used block words used in the above regions have a very wide range of regionalities, with the traces of small-area innovation.
