Welcome to Mr. Jun Yue’s website: Between the Lines
An early method of transmitting written coded messages was to write the secret information in invisible ink between the lines of a document. The recipient would then learn the information by reading between the lines.
The phrase came to mean an insight into the context. In cross-cultural communication, so many things are also between the lines. And a good cross-cultural communicator should not only be able to work with the lines, but also to navigate the ways between the lines.
