The concept of "long-term holding" is a "long-term investment" with stable performance in the true sense, that is, holding for at least two complete cycles. If you can't accept the cycle of more than 8 years, then you can consider holding it for 4-5 years (the highest probability of return), you must do a good job of "strategic timing" and never buy a fund at a high valuation! Buying at the right point and holding enough cycles is the key to the success of fund investment.
