The first section of " From Beginner to Proficiency " was about the contents of the shuttlecock court. This tutorial introduced the meaning, width, and distance of the lines on the court, as well as the height of the net. However, the exact meaning, width, and distance of the lines, as well as the height of the net, were not found in the search results provided. Therefore, I am unable to answer this question.
