I want to be a mold apprentice. Is it useful for me to go to Yuyao Mold City? Are there apprentices there?

The so-called mold city in China, like the mold village in Chang 'an, Dongguan, has gathered mold elites from all over the country and even the world. How can it be useless to learn in this environment? Apprentices are recruited everywhere, which is like having a life if someone dies, or facing extinction.
