Water shortage: This means that when the child is named, the name next to the water must be added, so that there is no lack of water and is conducive to the healthy growth of the child (if there is really a lack of water). Of course, you can also use a name that can bring about water (because the five elements are mutually reinforcing and restraining each other), but I think you can't use a name that can restrain water (which is harmful to children). This can prevent your child's name from having water in it and cutting off your financial path.
