classification rankings. In conclusion,this study may be not able to cover all the relevant literatures
in the field,reflect the entire subject matter of the field,and represent all the information of the
high cited journals.
For practical implications,the results can quickly,effectively and accurately identify the current
status of technology education field,find the most influential classical literature at different
stages (i.e. must read,the best,widely cited literature),as well as academics,and understand the
evolution of the past 20 years and possible future trends in the field of education research.
For originality,domestic and international technology education research rarely took the
data as long as 20 years to do analysis,and used citation analysis of bibliometrics to convert
static citation form into a valuable quantized dynamic form,reflecting the core literature of
technology education,knowledge flow and technology diffusion path,embodied the evolution and
development of the subjects in past 20 years. The results of this study will help the researchers
of technology education to quickly understand the development and status of international
technology research topics as well as predict the development directions of this field in the next
few years.

A new view of the origin of woodblock printing
CHEN Li ①a *

The invention of printing has changed the mode of cultural communication and advanced social
progress. Therefore,the origin of woodblock printing has been attracting the attention of scholars.
The invention and application of printing was deeply rooted in social and cultural conditions.
Social demands give impetus to applying an invention.
The engraving in China has a fairly early origin. The “in reverse” texts in the copper mould for
casting metallic coin in the Shang and Zhou Dynasties, stone steles in the Qin and Han Dynasties
as well as scriptures cut on rocks in the Han and Wei Dynasties are similar to woodblock carving.
Rubbing and seal techniques are the same as printing in principle, which can be considered one
of the origins of printing. Existing scriptures cut on rocks in the Eastern Han Dynasty, seals in the
pre-Qin period, rubbings of scriptures cut on rocks in the Northern and Southern Dynasties and
seals of Huangshen with as many as 120 characters inscribed on each of them in the Eastern Jin
Dynasty and etc. are some examples. Letterpress printing was used to dye textiles in no later than
the early Western Han Dynasty. Letterpress printing is exactly the same as woodblock printing in
principle and the quality of letterpress products was comparable to woodblock printing in the Song
