The national team, which is more general here, is the investment made by the state with the money of the state finance.

There are roughly the following categories

Securities, gold, Huijin and other enterprises directly invested by the state.

Social security, pensions and the like.

All kinds of corporate funds directly invested by state funds.

SASAC's asset investment and so on.

The part of these funds invested in A shares is the national team in the usual sense.
