How to be a trader in EU/LD/HK through a EU B School?

I am a Chinese in a university in China majoring in finance. I have finished my sophomore year. I hope to stay in Europe/London by studying some European programs like FSFM MFin, ESSEC GE to enter FO. Once I hope to work in IB, but now trader position is more attractive to me.
All of these programs can provide rich internship opportunities, which greatly increases the possibility of a non-local person to stay in Europe/London, and I hope to become a trader.
After studying at WSO, I found that mathematical and scientific skills seem to be very important for a trader, but I didn't study mathematics in depth in my undergraduate degree, though the good news is that I still have two years to make up for it. Could I ask you decent guys, what can I do to stay in Europe and become a Trader in London.
