Duan Yongping’s investment is not a list
1. Don’t go short – avoid the false zeroing pattern
2. Don’t borrow money – avoid the false zeroing mode
3. Don’t do things you don’t understand—invest within your circle of competence
4. Don’t take shortcuts – shortcuts are usually the hardest and longest way
5. Don’t blindly expand your circle of competence—the most common mistake investors make
6. Infrequent decision-making. ——The more decisions you make, the more opportunities you make to make mistakes
