Ni Hao Tsung-Min and welcome to Epic!
I love your strong tipping and edging movements. You also are getting into some great angles on your left turns.

This pic shows a lot of separation between the lower body and the upper body. Your right turns show some of the same positions, but not quite as strong. This is high performance skiing!

This is still a strong position, but we'd like to see the left turns and right turns with the same angles. Can you see how the upper body is closer to the same angle as the lower body in the above picture (right turn) versus your left turn?
Can you see the difference in the shoulder tipping between the two turns? I like to see the shoulders level as an ideal (a little lean is ok) when you are at this point in the turn. So here your right turns are a little better than your left. Sometimes it helps to focus on trying to keep both hands at the same height off the snow. When you finish a turn and are going across the slope, make sure that your shoulders are level to the snow (uphill shoulder higher than the downhill shoulder).

Here are a few more suggestions.
Can you see your rear end behind the heel piece of the bindings and your nose behind your toes? I'd like to see you taller at this point in the turn by bending your knees less, bending your ankles more and moving your belly button forward. The first suggestion is to
try skiing with your hands behind your back. If that feels uncomfortable, you need to move forward. The second suggestion is to try skiing without your backpack.
The next thing is that you tend to get stuck in the same position while you are on edge. This is commonly called "park and ride". In the picture above you are finishing a left turn and about to being a right turn. Your shoulders are facing in the same direction as your skis and your right hand is head of your left. I'd like to see the left hand further ahead of the right at this point and your shoulders facing more down the hill (i.e. to the inside of the new turn or where you are going). This concept is called turning into counter. Your shoulders should be facing the same direction as the skis only when both are pointed straight down the hill.
Let's go back to the first pic above. Can you see how close your feet are together? As you go faster and get more dynamic it is ok to let your feet get a little farther apart. This will increase your balance and let you handle the higher G forces in these turns better. The other thing this will do is let you work your legs more independently. As you get into higher performance turns, you will find yourself getting into "long leg/short leg" positions where one leg is bent more and the other is straighter. You can start to see this in the second pic where your right leg is bending while your left leg is relatively straight. I'd like to see that happening in your left turns too.
Most of these things work together. If your are having trouble doing one of the suggestions, try the others and you may find that one suggestion automatically make another suggestion happen. It looks like you are already having a lot of fun on the snow. Maybe after this next season you'll be skiing better than the guy in the second clip!
