Hi Chan! I can see the music at the link now. The number 101 appears over the treble clef. I think this is not a tempo marking but simply a measure number. I would make nothing more of it. There are some notes and writing in the upper left corner. What do they say about 8th note = ? Maybe we can get a better clue about tempo from that.
The decrescendo in line two marks the end of a phrase. Play more loudly on the first note (B natural) and less loudly on the second note (E natural on beats 4 and 5), which is the phrase end. Now even though what follows in the sixth 8th note beat is another E natural tied by a slur, it is musically a ‘pick up’, and it belongs to the next phrase. The dash tells you to make sure it sounds a little separated from the previous E natural, but still it wants to be UP bow as all pick ups should be. Maybe you will stop the bow, but maybe not completely. Give it a little impulse of speed in the bow to say ‘new beginning’ in the music. You have no dynamic marking next, but bring more sound than you did when ending the previous phrase. Grow dynamically into the new phrase of line two. But it is an ‘echo’ of line one, so keep it softer than you played it the first time. Phrase one in line one yells over the mountains. In phrase two, the mountain echos back. It is always distant and more gentle.
The diminuendo (dim.) near the end asks you to begin fading away, meaning ‘a decrease in loudness and intensity’. The decrescendo symbol, which follows, means the same thing, so continue fading away until the last note is complete.
