Oh I see. Thanks for sharing all of those.
It is interesting to point out that from the information we get here in Europe (and probably in any Western country), we are miles away from any concrete idea about how the situation is managed in China, beyond the "everyone is fully traced" item (I don't start into this debate here; just mentioning).
Thinking about it, such a strategy is not bad... except if you want to open your country to the rest of the world. In some sense, there is no free lunch and choices must be made. At this stage, honestly, I don't know which one is better.
