Yes. Occasionally as many as 20 or more infusions for really good stuff.

Normally most of us do multiple infusion sessions, so the tea just sits in the pot or gaiwan while we drink. If we will be pausing over night in the session, it's not a bad idea to stick the pot/gaiwan in the fridge till the next day and then maybe do a flash rinse in boiling water to wake it up and kill some bacteria.

These are good instructions for brewing vessels of 100 ml to 125 ml (3 to 4 oz). I personally skip the rinse, and when I do
rinse it is usually for less than 30 seconds or it is a flash rinse. Generally, you will do longer infusions for shu puerh and shorter infusions for sheng, but the the Puerhshop guidelines are good place to start out with a new tea.
Each tea will be happiest with a little different treatment, so be flexible. If it is coming out too bitter or astringent, shorten the infusion time; if it is too bland, lengthen the time. It it is BOTH, increase the leaf a bit and shorten the time.
