Tea bags with hot water or lukewarm water?

Tea bags are steeped with hot water.

Tea bags are the most popular drink nowadays. Generally speaking, they are brewed with hot water. The correct way to brew tea bags is to pour hot water first, and then put the tea bags, otherwise the air will soak into the tea bags, and the tea bags will remain suspended in the water. When making tea with tea bags, you need to pay attention to boiling water and don't stir the tea bags, otherwise it will become bitter. It is best to use a cup with a lid for the container of the tea bag, so as not to make the aroma of the tea run away. Another thing to note is that you should not use a thermos cup to make tea bags.
