What are the feelings of Korean learners and Japanese learners?

Korean writing is fast, whether it is taking notes, shorthand or drafting, it will be fast, and when writing, you can put books between Chinese and Korean, that is, Chinese and Korean are mixed together, and other languages cannot be so compatible with Chinese. Japan is more developed than South Korea and has stronger national characteristics. Learning Japanese for a long time is easier to adjust one's personality than Korean, not that one will become pro-Japanese, but that one prefers "independence, courtesy and preciseness".
