This reminds me of my experience in developing "Felo Search", which was truly crazy. In the past year, I hardly dared to think about projects related to general search engines. Such experiences are common, just like when you achieve success in the field of technology, people will also encounter unfamiliar things or situations in life and learn new knowledge and skills from them.

This kind of experience can be seen as a part of growth, no matter how experienced we are in a certain field, we will always encounter new challenges that require learning, I wish you good luck!
