Are you a student in the midterm?
The following is the analysis:
First of all, the eighth century is 70 1 year, 10/day to 800 1 day, and February 1 day.
A. Calligraphy is a Chinese character written by the Japanese. We can see that Japanese people love Chinese characters and calligraphy in China, and they may feel sad that they have no national character, which is an important national factor.
C. During Tuigu (593-629) and Shoto Kutaishi's regency, Japan began to send "Sui envoys" and "Tang envoys" directly to China, and a large number of foreign students and monks studying abroad took the initiative to learn China culture, becoming the first country to send people to study in China. The Sui Dynasty was also the period when China began to receive a large number of overseas students. In the fifth year of Kaiyuan (7 17), Kibi No Asomi Makibi came to China with the envoy of the Tang Dynasty. He studied in Chang 'an with four teaching assistants, Zhao, and was proficient in five classics and three histories, calendar calculation, criminal law, omission, military system, array method, phonology, calligraphy and other arts. He studied in the Tang Dynasty 17, and returned to China with 1700 China classics in November of the 22nd year of Kaiyuan (734). For the inheritance of Japanese culture, one of Kibi No Asomi Makibi's most important historical achievements is that he created Japanese katakana based on some Chinese characters. So the title didn't say what year it was, only the 8th century. It can't be assumed that it was a year before or a year after the invention of Japanese, nor can it be said that they didn't have their own characters at this time.
D The only Japanese who came to China in the 8th century AD, had access to Chinese characters and could write good calligraphy were the envoys of the Tang Dynasty and outstanding scholars. So it is very likely that it was written by an envoy of the Tang Dynasty.
So it can't be B.
First, the inconvenient transportation was an important objective factor.
Second, before the 7th century, Japanese people mainly relied on the spread of China immigrants to learn China culture, and it was not until 608 AD that they set a precedent for sending delegations to study abroad. Shoto Kutaishi attached great importance to the development of relations with the Sui Dynasty, and hoped to actively introduce various advanced cultures and systems from China through this measure, so as to establish a sound national system. At that time, Japanese culture was still very backward and basically belonged to the stage of learning from others.
Third, communication is only official and unilateral, that is, we need to learn from each other in close cultural exchanges and learn from each other in various fields in a relatively large range.
