In the Tang period there was 
chih (_??_) in the official system (_??__??__??_). (The word 
chu-chih (_??__??_) means all kinds of 
chih (_??_).) 
Chih was a name of the people who had special technical abilities and worked at each government office The position-class of it was in accordance with 
Liu-wai-kuan (_??__??__??_).
In the official system of our
 RYO code (_??__??_), there was a post called
 TOMOBE (_??__??_). This is a name of the people who belonged to a government office also with special technical abilities. Their position-class was ZONIN (_??__??_). There were _??__??__??_, _??__??__??_, _??__??_, _??__??__??_, _??__??__??_, etc. in the system of chih, and, in the system of TOMOBE there were _??__??__??_, _??__??__??_, _??__??__??_, _??__??__??_, _??__??__??_ etc. Those two are very similar to each other both in contents and in expression. The people of TOMOBE were engaged in all kinds of manufactures, but when they could not do alone, as they had the people called
 ZOKO (_??__??_) and
 SHINABE (_??__??_) under them, they used
 ZOKO and SHINABE. This connection between TOMOBE and
 ZOKO or SHINABE is very similar to that of
 chu-chih and 
tsa-hu(_??__??_) or 
kuan-hu (_??__??_) in the Tang period. Comparing those matters described above, we can find that our system of 
TOMOBE, 
ZOKO and SHINABE in 
RYO code had been transferred from the system of 
chu-chih, 
tsa-hu and 
kuan-hu in a code of 
Tang Dynasty.
Before the Reformation of the Taika era'
 TOMO-NO-MIYATSUKO (_??__??_), a chief of 
BE (_??_) which was a group of the people of special technical abilities, had serv-ed at the Imperial Household with the people of this group of BE. (
BE (_??_) was also called 
SHINABE (_??__??_).) But at the time of the Reformation of the Taika it was abolished, and, as Chinese
 RITSURYO code introduced from China was established in Japan, 
 TOMONO-MIYATSUKO came to be named 
TOMOBE and newly started as 
ZONIN in official system.
 SHINABE came to belong to each office with the people of 
ZOKO that system was also newly transferred from China. I think that the system of 
TOMO-NO-MIYATSUKO and 
SHINABE before the Reformation of the Taika era was not inherent in Japan but was influenced by the system of China. The reason of it is that
 pu-ch'ü (_??__??_), an origin of our 
BE, mainly came from the name of a supply section of people (the lowly), who belonged to a powerful clan of the 
Wei (_??_) 
Dynasty and the 
Chin (_??_) 
Dynasty, pu-ch'ü; and after that, a system of
 Liu-wai-kuan was made in Northern
 Wei (_??__??_);a system of 
chu-chih which accorded with 
Liu-wai-kuan was established in the 
Zui (_??_) Dynasty and in the 
Tang Dynasty ; and it is said that 
kuan-hu and
 tsa-hu which consisted of the people attached to each government office as exclusive laborers came to be recorded in history about a time of the 
Chin Dyn asty, and those systems were established in the last days of 
Zui Dynasty or at the time of the
 Tang Dynasty ; then, comparing changes of the system of Japan with those of China, we can see that the system of
 TOMO-NO-MIYATSUKO and
 BE (
SHINABE) before the Reformation of the 
Taika era were established under the effect of the system of the powerful clan and
 pu-eh'ü in China.
