Hi @yiwen101 thank you for the changes! Some more formatting errors and some minor nits and we should be good to go :)

Thank you so much for the meticulous review, I feel so bad forcing you pointing out so many formatting issues, especially during the CNY holiday. I have made the requested adjustment (and some other minor changes). Thank you for your reviews and help again.
