I am very happy to be chosen for this project for the next 2 months.

My next plan is to fork Seata into my account, I will make a Pull Request when progress is made, and invite my mentor for a code review.

At the same time, I will report my progress under this issue every week, and will invite my mentor to give an assessment of my progress @jsbxyyx .
