Japanese: new コロナィルス
Introduction to Japanese:
Both Hiragana, Katakana and Chinese characters in Japanese originated from the learning and changes of Chinese culture by the Tang envoys who came to Chang 'an that year. Many commonly used words in Japanese are not different from China people's language habits, so even a China person who doesn't know Japanese at all can guess the general meaning by reading Japanese newspapers.
In all foreign languages, the investment-return ratio of learning Japanese is definitely one of the best in terms of time investment and language mastery.
It is difficult to speak Japanese, mainly in listening and speaking. As for written grammar and vocabulary, China students who are used to exam-oriented education are already familiar with it.
