I am a beginner at guitar. I was looking at a guitar tab for a Chinese song but I have trouble understanding it. x means to pick the string where it is drawn, but what do the other symbols mean in this context? Can anyone help me to interpret the action to be executed where there are zeros and the symbol that looks like y, and the 4 in the second line and 1st bar, and the curve in the second line and last bar. What do they mean? And does the arrow in the second line and last bar mean a strum starting from the 5th string?
Please advice.
