That is to say, you own the company's assets as much as I own the company's shares, and you also have the right to make profits when you realize profit distribution, and also have the right to make decisions when the company makes major decisions; The shares of listed companies can be sold and realized through the secondary market.
For non-listed companies, shares are also a form of assets and can be realized. For example, if someone is optimistic about your company and wants to take a share, you can negotiate the share transfer price. After the negotiation is successful, you can trade, how many shares you transfer and how much money you get.
I hope it helps you.
