"Leaping" is clearly leaping for joy working for EF Changchun. He has a guaranteed career structure there, and can earn good money leaping around in front of his students. EF Changchun is his ideal employer, and he likes the city despite the cold winter weather. Let's back off and leave him be. It takes all sorts to make society. We needn't be so critical of him and training schools in general. Live and let live, please, I beg you. I believe they can not all be bottom of the barrel, some must be even be par excellence, though I personally prefer the public education sector here in this wonderful country.
