When I was a child, my family was poor, and I rarely went out to buy snacks I wanted, or asked my parents to fry some cakes. In fact, people often go to the countryside to sell oil cakes or fried dough sticks. I always want my parents to buy some, but I know they can't buy them every day because of their limited conditions, but occasionally they buy some for us to eat. They often make their own omelets, which is very simple. I'll put some flour, slide an egg, and then add some salt and onions.

When I grow up, I go out to work, and I often see people selling eggs and filling cakes on the street. At that time, I bought one every day after work, and I especially liked it. I don't know how they did it. Once I saw my boss cooking there, and then I asked him where he bought this cake. How can I tell you when you are doing business? I happened to see this kind of stuffing cake when I went shopping in the supermarket once. I didn't buy it back, so I tried to make it myself. Every time I just want to beat the eggs in, the cake breaks. I don't know what happened. How can others do it easily? Not when it comes to yourself, so many things don't happen at first sight, because the skin is so thin that it will break if you are not careful. I tried to pour the eggs in every time I opened them a little, but I didn't expect to fail. In fact, egg filling cake looks very simple. I just need to poke a small hole and pour the eggs in, but I fail every time.

So you don't necessarily know what others look simple. Practice makes perfect. Everyone may have a sense of accomplishment in his own field, but doing other people's things may not be possible. Many things seem simple. In fact, people are skilled and not so eager to learn. Although you can't think everything is complicated, don't be too conceited. We must learn everything with an open mind, even if it is.
