I wouldn’t personally call “Gong Fu Cha” a ceremony, more like a “discipline” since that’s sort of the idea behind “Gong Fu” its the idea of get better at something doing it over and over again, so best translation for would be a discipline. Unless you meant Japanese tea ceremony, but that’s not really for tasting the tea its more like the tea is used for symbolism sake like say how wine is used in mass.

I also don’t think it has that many steps? Preheat the vessels using water at the temperature you’ll be using for the tea, pour that water out, put tea leaves rinse the leaves with the water pour that out, steep the tea after say 10s pour that water out into a secondary vessel (probably a gong dao bei) pour that tea liquid into your small tasting cup and slurp to taste. Pour some more until you need start a new steeping, do what you did previously just slightly longer steeping time.
