Wit sister actually refers to an "endurance base" that has experienced bulls and bears and has been stable for a long time. For example, Everbright Prudential's Everbright New Growth Fund has a good experience and stable performance. Everbright's new growth operation time has exceeded 13 years, and its short, medium and long-term performance ranks in the top 1/4, while similar funds rank in the top 1/4 in terms of short, medium and long-term data dimensions, which is less than 5%. It is a veritable "endurance base".
