It's probably the innovative invention of chopsticks.
I believe the stories of da ji and Zhou Wang are household names. This Shang Zhouwang is very cruel and lewd, extremely fatuous, full of delicacies and delicacies. Da ji, on the other hand, is a woman who combines beauty and wisdom and does whatever it takes to achieve her goal. Da ji was demonized as a fox in the Romance of the Gods, and Zhou Wang was constantly induced to do some cruel and heinous things with her beauty, which finally turned Shang Zhouwang into a "monster" who could not control herself.
Let's not talk about the truth or falsehood of da ji and Shang Zhouwang for the time being, but in the process of pleasing Zhou Wang, da ji really put some thought into it, otherwise it wouldn't be so easy to capture Zhou Wang's heart for a long time and let Zhou Wang willingly use it. According to legend, Zhou Wang not only loves beauty, but also loves food. Every meal must be accompanied by beauty, and every meal must be to his taste. If the food doesn't taste right, the cook will be killed directly. In order to flatter Zhou Wang, da ji not only serves him for dinner every day, but sometimes cooks for him personally and cooks delicious food for him.
In order to cook the food well and achieve Zhou Wang's love and appreciation. Whether it's da ji's own cooking or chef's cooking, da ji will try it before eating in Zhou Wang to see if it tastes right and whether it suits Zhou Wang's appetite. On one occasion, the servant just served a steaming dish, and Zhou Wang was about to eat it with his hands. da ji thought it was over, and Zhou Wang would be burned if he ate it, which would affect Zhou Wang's mood. So she immediately thought of a way, that is, pick up the food with the Hosta on her head and send it to Zhou Wang's mouth. In the process of picking up and conveying the food with Hosta, it is naturally not so hot, and it is just the right temperature in Zhou Wang's mouth.
This method spread slowly, from the initial hairpin to chopsticks made of bamboo and wood, which is also the origin of the chopsticks we use now.
