Some analysts dismiss the fear that a full blown stock market collapse could precipitate a wider economic shock.
"The stock market is too small, too tiny, completely irrelevant," Chen Long, China economist at Gavekal Dragonomics tells me. "It accounts for just 5% of Chinese household wealth and anyway the market is still up on where it was last year."
Much more could yet be wiped off the value of Chinese shares, it would follow, before anyone needs to panic, least of all the government. So perhaps, if this view is correct, Beijing's actions are motivated by the need to contain the political fallout, rather than the economic.
In the middle of an already tricky slowdown in GDP growth the last thing it needs is hordes of mom and pop stock traders taking to the streets. And so far, at least, that part of the strategy might be working with little sign of any anger.
Despite her already heavy losses, Lin Jinxia's plan is to hang onto her massively devalued stock in the hope it rises again. "I believe the government will come up with the right strategies," she tells me.
