The best answer: jewelry is used to make money, PK is used to do projects, and WLK can make motorcycles. But motorcycles always feel neither fish nor fowl when they run. Few people ride motorcycles in tablecloths. We seldom ride motorcycles anyway. If you are advised to learn tailoring+engineering just for fun, tailoring can make flying carpets, and engineering can make motorcycles and airplanes, which are exclusive to tailoring and engineering. If you want to make money, you can learn from the tailor+gem, and the tailor can wash the cloth later to make money. Not to mention gems, all the gems produced in the later period make money by LZ. You should practice jewelry first. Jewelry earns a lot of money. If WLK is used, if the project can make motorcycles and the tailor can make flying carpets, it will be fun! If you are MS, you'd better be a tailor. The project is more useful to play the battlefield and arena! LZ, weigh it yourself!
