lead by example
The best way is for parents to set an example for their children. Children are born to imitate little geniuses, and their words and deeds will be influenced by their parents. If parents can consume rationally in daily life and don't follow the trend, children will naturally imitate and develop good habits.
Correct view of money
It is the key to actively guide children to establish a correct view of money. You know, a person's behavior often stems from his thoughts. Therefore, parents need to guide their children patiently and help them understand the value of money and use it correctly. Only when they truly understand that "money should be spent on the cutting edge" can they avoid unnecessary comparison and waste.
Good living habits
It is also important to help children develop good living habits. A child with good living habits will naturally know how to arrange his own consumption reasonably, and will not blindly compare or spend money indiscriminately.
