Is it normal for my Chinese Elm to get 2 or 3 leaves brown like that? He gets full sun everyday and i water twice a day when the soil gets dry.
Also i saw some spider webs on my leaves. What can i do about it?
Thanks in advance.

At least it is outside, twice a day seems too much, unless you are in a tropical country and the tree is drying out that fast. I can't see any brown leaves but it is normal for any plant to lose some leaves. It could do with pruning from what I can see there are a lot of over long branches. It looks like there is a large root over the surface am I right?

yes you are right. It is pretty hot in these days. Between 12am and 18pm there are 24-26 degrees Celsius.
