The so-called passive income, that is, in addition to your main business, other income is considered passive income. Of course, part-time jobs don't count, so you know what passive income is. For example, you have bought a house, or antiques, stocks, funds, gold, silver and other investment products with room for appreciation.

As far as the current market is concerned, there is little room for the appreciation of houses, and antiques are hard to satisfy, let alone gub, let alone the decline at this stage. Only consider money, or gold or silver.

Of course, these are actually investments now. If it is too complicated, you can consider saving your usual income in installments, or saving Baifubao, Yu 'ebao, and Licaitong. I hope I can help you.
