Both engineering and jewelry need the basic material "mine"

Most people are mining+engineering or jewelry.

If you really want to practice together, I suggest you do so. Mining+jewelry first, practice all the jewelry, then wash away mining and study engineering. This can save a little money.

If you have another number, that's easy to say. Let another number specialize in mining, and this number can be double-cultivated.

Play with your heart, play wonderfully, and play with personality! Just after the New Year, I wish you a happy New Year and all the best!
