When i ask before, i get the answer is point number is too big.

Bastard Programmer from Hell
If you can't read my code, try converting it here[^]

Thread th = new Thread(() => fun1(x, y => fun3(y, z)));

Action<int> call = y => fun3(y, z);
ThreadStart start = () => fun1(x, call);
Thread th = new Thread(start);
