I consider learning as a lifelong process. I have interests in multifarious fields. For now, I spend most of my time on learning data analysis, economics, piano and preparing myself for risk management work. It has always been a pleasure for me to share with people what I have learned in real life or college. I hope this website can help people find something useful for them.
