I heard that tea heads are stamped out with their feet, right? Which is better, tea head or tuocha?

The technology you heard about existed when processing tea. It used to be in some private teahouses in Yunnan, but now it is no longer used by regular manufacturers. Imagine how much tea can be processed in a day if all the manufacturers who need to produce tea in batches step on it with their feet. Moreover, the existing private tea houses also steam the tea leaves, put them in the female mold, press the male mold on it, and press the tea leaves with their feet. So you have to rest assured in this regard.

As for your supplementary question, any tea used to lose weight is auxiliary and needs long-term persistence to be effective. If you decide to use Pu 'er tea to lose weight, the results of colleagues around you are that the effect of using Pu 'er raw tea is still good, and it will not get angry in summer.
