I have moved out of China last year because I had to realise that things go downhill in education there and that I should better find another more suitable position somewhere else - better pay, less hours, a decent job

(teaching graduate students and supervising their theses)

I would pay to watch THAT.

I even have enough means to assist the less fortunate in doing some additional (unpaid) teaching at tertiary level in a volunteer project which is free of charge to students in need.

Canonisation may be just a step away. Just think,!Saint Turnip!

Blow trumpet, blow. All wind as usual.
