Is it okay to put a jade toad in a car? How to place it? Please give me some advice from a Feng Shui expert! ! Thanks!

It depends on whether your car is a commercial vehicle or a private car. Toads attract wealth and treasures, but they are not a tool to ward off evil spirits. I think you still want the people in the car to be safe and smooth. The more popular method nowadays is to hang a string of beads or a jade pendant with auspicious meanings on the rearview mirror. Such auspicious objects can ensure the safety and smoothness of the drivers. Speaking of which, it is best not to keep things like Pixiu or lions in the car. Such things are fierce and protect the owner, and are also a deterrent to others, and may lead to lawsuits.
