A-shares market is really good

The one I recommended to my wife at the beginning of the year has already doubled
My returns this year haven't beaten my wife's
My wife said she wants to learn about our circle, I said the volatility is too high, you can't handle it, why not buy some A-shares 😂
She asked me how to operate, I said no doubling without getting back the principal, 😂 as if I had returned to the last bull market.
