Appreciate Prof. Chan's effort. The sad thing in HongKong is the extremely expensive land that causes the expensive living cost in HongKong. One of the negative side effect is teens don't spend time on STEM. STEM is one if the pillar of R&D whatever Medical, Engineering, BioChemical.... Because, there is no brilliant prospect in STEM related careers., students of pure Science/Engineering in University can't find high paid jobs to survive. Consequently, less and less students don't go to Engineering School or Pure Science school in University.
