[LUS8806]

Hi there,

I find the following wrong codes in "qlib_data/cn_data/instruments/csi300.txt"
SZ688008
SZ688009
SZ688012
SZ688036
SZ688111
SZ688126
SZ688169
SZ688363
SZ688396

These stocks are listed on shanghai exchange and should be SH688***

Thanks,

That's likely because something like this in somewhere : return f"SH{symbol}" if symbol.startswith("60") else f"SZ{symbol}"
