Why not study whether people are liars? Spend your mind on how to study barbecue well. Actually, making a barbecue is very simple. You can know what it tastes like when you try to eat others, and you can also see how others operate. If the barbecue is delicious, you must be patient. Dried meat takes time, and the smell of fat is attractive. Some materials need to be cured and some materials need to be baked slowly. Many of these are practical experiences, and learning cannot be learned at one time. It is better to bake more and try more.
