The difficulty of this passage lies in the left hand, because it is impossible for the left hand to play more than two upper and lower 8-degree voices at the same time (both high and low notes A and E should be played). Therefore, the author arranged this way: add a small forward pitch before the bass of the left eighth note in advance, and connect the time values of the two with hyphens. In this way, the contradiction is solved: let the left hand advance a little (in fact, at the last moment of the first paragraph of the solar term, the bottom leaning sound is played in advance), and then you need to step on the sustain pedal at the same time to maintain and continue the bass (also note that two sustain lines are marked on the bass A and E of the octave on the spectrum, indicating that their duration can be longer than that of the octave! Almost at the same time, the left hand should quickly move to the right to the position of the main melody above, and start playing the main melody at the "beat point" of the first beat in the next section. At this time, the branch of the right hand (the semitone chord of the triplet) should also start playing in synchronization with the main theme of the left hand. Because the left hand needs to play a "time difference" to complete the fast and accurate long jump, it is necessary to train the left hand repeatedly until it is proficient, so as to ensure the smooth progress of the whole music at this time.
