Sorry, Ji... If you're still needing help with your monkey, try this:
Break it down into little parts. When you're comfy with one part, then add a little. Play with it until you feel comfortable, then add the next thing. If you're getting tired or frustrated, move on to something else until you have a chance to rest.
Find something wide and solid, maybe just a little lower than your hips to start. [table, loading dock, wide wall, bed?].
Bend over. Put your hands on the object close to the edge to start with.
Arms straight, hands a little in front of shoulders. Keep your head up and forward.
Practice jumping your hips above shoulder level. Start with single jumps, then increase it to 2 or 3 in a row.
Add tucking your legs [like Michael said]. Again, start with singles.
Now your goal is to land your feet on the object [like Sala said].
You'll want to start with your hands a little more forward.
Instead of a straight up and down jump, you want to jump a bit more forward.
So land either in a QM position, or if you've got the power, land on your feet in squat position.
Then add the approach. Start with a single step. Then try a couple steps. Then walking up. Gradually increase the distance and the speed as you feel comfortable. Play with different objects, different heights, different angles of approach.
When you're comfortable monkeying ONTO things from a run, it won't take long until you're monkeying OVER things. Take your time. Have fun. Enjoy the process and the newness. Train safe, train hard. I'm sure it won't be long...
