I told my mother to learn something. I decided on the guitar of the instrument, but I can't read the music. Look at the 2 in the third line. What does it mean?

The two symbols at the beginning of the score are rests. . . Looking at the guitar score is like thinking of the six-line score as your six guitar strings. Fingering is played from right to right in turn, and the string position of each number is the position of your six guitar strings. For example, the third string from top to bottom in the score is the third string from bottom to top in the guitar. His number is five, so he counts from the piano head to the right. .
