This topic is too big and wide. You should narrow down the scope first and choose a starting point that you like or easy to write. Do you want to write the history of ancient communication in cross-cultural communication? Or is it a modern Sino-Japanese exchange? In short, first find a carrier, whether it is the influence of trade, literature or the spread of art. This is the first consideration. After confirmation, you can look for relevant papers, which is called advanced research. If you are in a university, you can inquire through the full-text database of the library and download it for free. Good luck.
