What is said above is the definition of narrow trust in China.
Trust is more broadly defined internationally. You can refer to the testamentary trusts of Anita Mui and Sam Dianxia.
Trust is credit entrustment. Anita Mui’s example can illustrate the problem: Before Mei passed away, she asked HSBC Trust to enter into a trust contract to establish a trust fund. The contract stipulated that HSBC Trust had the right and obligation to charge a certain handling fee. Later, a certain amount of living support will be paid to the mother and siblings at a fixed time in accordance with the trust fund contract. If the trust contract stipulates investment terms, it is an investment trust fund; if it is a public welfare trust fund, it is a public welfare trust fund, and so on.
A single fund established by a domestic trust company after determining investment projects, income, investment direction and other factors can be called a trust fund product. This kind of trust product can be "purchased". This establishment behavior of the trust company is called For "Separately Created".
The definition is complicated, I hope it can help you.
