Training to broaden work horizons. Broadening one's horizons is self-evident for improving one's position in the workplace. For people in the workplace, it is fundamental to hold their own turf, and opening up more career development channels is the most effective way to ensure their competitiveness. In this sense, those trainings that broaden your horizons and learn the latest and most cutting-edge knowledge are also very useful. This year, for myself, there is another training that is very useful. The company invited Professor Lv Tingjie, Dean of School of Economics and Management, Beijing University of Posts and Telecommunications, to give us a lecture, mainly on the application and development of blockchain. Everyone is familiar with the blockchain now, but what is the ins and outs of the blockchain and what can be done? Through Professor Lu's lecture, I got a clear understanding and found it really useful.
