Hi Lin,
These local names with extra numbers look strange.
You introduced these numbers in order to fix naming conflicts.
You also can avoid these conflicts by refactoring the code.
Some of these fragments can be refactored to become a separate methods.
I do not want to push hard on you with this but it is just something to consider to simplify the code and avoid such naming problems.
Thanks,
Serguei
