1. Double-income industry (mainly making money, but very hard)

2. An acquisition industry or intensive industry (such as enchantment) and a manufacturing industry (the two occupations match each other, and the collected materials can be manufactured, and the income is ultimately for manufacturing)

3. Dual manufacturing (the most profitable, fastest-upgrading, but most expensive combination, because all materials can only be purchased)

For soldiers, you should choose the second or third collocation. Only medicinal materials are collected and mined in the collection industry, and the project needs to be mined. PVP earns a lot of money, and alchemy needs medicine, but I personally don't recommend learning alchemy. For PVE, the biggest income is jewelry, and the sales volume is also very large. So jewelry is the best choice to make money or upgrade your own equipment, but it is a bit difficult to upgrade jewelry, and there are too many drawings. Of the three manufacturing industries, tanning and tailoring, only forging is related to soldiers. If it is to make money, the income is hard to say. It is very difficult to start with advanced drawing. People who have the ability to make advanced drawings already have advanced equipment. Most people who learn forging still want to equip them with two extra holes set with gems. With these two holes, the income of jewelry will not be matched by other majors.

Generally speaking, engineering, forging and jewelry are very good soldiers PVE and PVP. Personally, for PVE, jewelry, forging and PVP, jewelry and engineering should be taken into account, and the best combination is jewelry and engineering.
