In this book, we discover the code of honor of the 'portenos' dancers of the Tango Milonguero, who have remained 'uncontaminated' by the tourism surrounding the Tango, the major part of whom are more or less 70-80 years old. Their behavior reflects concepts that were already spoken of in ancient China! Let's discover them together by following in the footsteps of the Chinese philosopher, Lao Tse, and of los Viejos Milongueros. You will surely be astonished by what you discover!
