Is Asian traditional archery difficult?

Yes it is.  First traditional archery means, no sight to help aiming, no arrow rest to help arrow flying.  It's just you, the bow, and arrows.  You shoot instinctively, which means, you do not aim.  You open both eyes, you look at the target, and you shoot.  Everything is muscle memories, which means you need to practice a lot.
It's like playing golf or basket ball.  When you play basketball, you just look at the net, and your mind and body know how much strength, and angle to shoot the ball in the net.  It's the same concept.
It's hard, but when the arrow hits the target, it feels very good.  When you shoot, when the arrow started to leave your hand, you can tell whether it's a clean shot or not.  The sounds, the feel, the vibration, everything is different when you have a clean shot.

It's so much fun.

My first 40 yards shoot

When I got to the range, there were people having a lesson on 10-15 yards target range.  So I headed to 40, 45, 50, 55, and 60 yards range.  I felt the 40 yards was so far.
I shot my first arrow, and it flew way over the target, and disappeared.  I tried to find it, but I could not.  Damn, I lost my arrow from my first shot!!
I should have started shooting it on 10 yards target....oh well, since I was waiting for the lesson was finished.  I kept practicing on 40 yards target.
One round was 11 arrows since I lost one.  I think I shot 6 rounds. 

My first attempted....only one arrow hit the target.

 Getting there

My 6th round

Let me explain the first feeling of shooting an arrow, and watching it flying to a target.  It's fantastic.  I do not know how to explain it, it's just a joy to see my arrows flying, and hit the target.  It's very addicting!

Redwood Bowmen Club

About 20mins away from my home, there is a range called Redwood Bowmen club in Oakland.  It's right next to Chabot space center.  You park your car at the bottom floor of the parking lot, and just walk outside.
Then you will see this beautiful outdoor range, that has 3 different trail 3D target courses, and variety of ranges of targets.  I love this place.  It's perfect when you visit here in the morning.

My 3rd thumb ring

After I failed to make thumb rings, I tried it again.  This time, I only used dremel tool to shape it roughly.  After that, I only used files and sand papers to make it to fit in my thumb.  It took at least 6 hours.  The  result was, perfect.  I absolutely love it.

The pictures are the first version.  Now it's much thinner, shorter, and less bulkier than this, but the shape itself is the same.

My new arrows

Here are pictures of my new built arrows.  Beautiful!

Fletching

I glues 3 4" feathers on each shaft.  Since I bought a right helical fletching jig, and the feathers, the arrows suppose to rotate clock wise when they fly.

I am a visual person, so I just go to youtube, and type "how to fletch", and you will find many how to vidoes.

Making new arrows

I ordered arrow shafts, a fletching jig, inserts, nocks, feathers, a glue, and points to make my own arrows.  I am a fan of customizing, and having things only for me.  Customizing, creating own arrows were so much fun, and I really liked it.

I ordered all the equipments and tools from Lancaster archery.
There are more online shops for archery.  You can google it.
