I I have just watched your talk and painfully watched the advert reminding me what I cannot have. Seriously, the 4th level is to fight with wisdom, talents and all those intangible things like will, determination, luck, ambition. A Primary 4 teacher enlightened me on several things. One of that was the story of a successful accomplished student who learned everything that there was from the teacher. He challenged his teacher. The teacher was boxed into a corner. Situation was dire. There was a discarded umbrella stem within reach. The teacher picked it up and regained upper hand. At the end the teacher commented on the battle saying “fortunate for me I have not taught you the umbrella stem yet”. In the case of The Hong Kong People v. Carrie Lam we need to find that umbrella stem and perhaps more. Wonder if you would publish a talking book version with your notes. The reader's voice must be distinguishable from yours. I will be the first to buy it because the adverts are hurting my ears.
