Writing system for Chinese in the Perso Arabic script

Xiao'erjing is written from right to left, like other writing systems using the Perso Arabic script. The Xiao'erjing writing system is unusual among Arabic script based writing systems in that all vowels, long and short, are explicitly marked at all times with Arabic diacritics; this means that Xiao'erjing is technically an abugida, in contrast to the abjad classification of most Perso Arabic script varieties. This is also in contrast to some other Arabic based writing systems in China, such as the Uyghur Arabic alphabet, which uses full letters and not diacritics to mark short vowels.

Xiao'erjing does not have a single, standard name. In Shanxi, Hebei, Henan, Shandong, and eastern Shaanxi, as well as also Beijing, Tianjin and the northeastern provinces, the script is referred to as Xiǎo'érjīng, which when shortened becomes Xiǎojīng or Xiāojīng (the latter Xiāo has the meaning of "to review" in the aforementioned regions). In Ningxia, Gansu, Inner Mongolia, Qinghai, western Shaanxi and the northwestern provinces, the script is referred to as Xiǎo'érjǐn. The Dongxiang people refer to it as the "Dongxiang script" or the "Huihui script"; The Salar refer to it as the "Salar script"; The Dungan of Central Asia used a variation of Xiao'erjing called the "Hui script", before being made to abandon the Arabic script for Latin and Cyrillic. According to A. Kalimov, a famous Dungan linguist, the Dungan of the former Soviet Union called this script щёҗин (şjoⱬin, 消經).

Since the arrival of Islam in Tang dynasty China beginning in the mid 7th century, many Arabic and Persian speaking people migrated into China. Centuries later, these peoples assimilated with the native Han Chinese, forming the Hui ethnicity of today. Many Chinese Muslim students attended madrasas to study Classical Arabic and the Qur'an. Because these students had a very basic understanding of Chinese characters but would have a better command of the spoken tongue once assimilated, they started using the Arabic script for Chinese. This was often done by writing notes in Chinese to aid in the memorization of suras. This method was also used to write Chinese translations of Arabic vocabulary learned in the madrasas. Thus, a system of writing the Chinese language with Arabic script gradually developed and standardized to some extent. Currently, the oldest known artifact showing signs of Xiao'erjing is a stone stele in the courtyard of vertical align=sup in Xi'an. The stele shows inscribed Qur'anic verses in Arabic as well as a short note of the names of the inscribers in Xiao'erjing. The stele was done in the year AH 740 in the Islamic calendar (between July 9, 1339, and June 26, 1340). Some old Xiao'erjing manuscripts (along with other rare texts including those from Dunhuang) are preserved in the Institute of Oriental Manuscripts of the Russian Academy of Sciences in St. Petersburg, Russia.

Xiao'erjing can be divided into two sets, the "Mosque system" and the "Daily system". The "Mosque system" is the system used by pupils and imams in mosques and madrasahs. It contains much Arabic and Persian religious lexicon, and no usage of Chinese characters. This system is relatively standardised, and could be considered a true writing system. The "Daily system" is the system used by the less educated for letters and correspondences on a personal level. Often simple Chinese characters are mixed in with the Arabic script, mostly discussing non religious matters, and therewith relatively little Arabic and Persian loans. This practice can differ drastically from person to person. The system would be devised by the writer himself, with one's own understanding of the Arabic and Persian alphabets, mapped accordingly to one's own dialectal pronunciation. Often, only the letter's sender and the letter's receiver can understand completely what is written, while being very difficult for others to read. Unlike Hui Muslims in other areas of China, Muslims of the northwest provinces of Shaanxi and Gansu had no knowledge of the Han Kitab or Literary Chinese, they used Xiao'erjing. Xiao'erjing was used to annotate foreign language Islamic documents (in languages like Persian) using the Chinese language. Xiao'erjing was used mostly by Muslims who could not read Chinese characters. It was imperfect due to various factors. The differing Chinese dialects would require multiple different depictions with Xiao'erjing. Xiao'erjing cannot display the tones present in Chinese, syllable endings are indistinguishable, i. e. xi'an and xian. Xiao'erjing was much simpler than Chinese characters for representing Chinese.

In recent years, the usage of Xiao'erjing is nearing extinction due to the growing Chinese economy and the improvement of Chinese character education in rural parts of the country. Chinese characters, along with pinyin, have since replaced Xiao'erjing. Since the mid 1980s, there has been much scholarly work done within and outside China concerning Xiao'erjing. On location research has been conducted and the users of Xiao'erjing have been interviewed. Written and printed materials of Xiao'erjing were also collected by researchers, the ones at Nanjing University being the most comprehensive. is leading a project in Japan concerning Xiao'erjing. Books are printed in Xiao'erjing. In Arabic language Qur'ans, Xiao'erjing annotations are used to help women read. Xiao'erjing is used to explain certain terms when used as annotations. Xiao'erjing is also used to write Chinese language Qurans. A Dachang Hui Imam, Ma Zhenwu, wrote a Qur'an translation into Chinese including Chinese characters and Xiao'erjing.

Xiao'erjing has 31 letters, 4 of which are used to represent vowel sounds. The 31 letters consists of 28 letters borrowed from Arabic, 4 letters borrowed from Persian along with 2 modified letters and 1 extra letter unique to Xiao'erjing.
