Why can't Taojiang form amber?

Because the burial environment of amber should be long-term stable, because even if amber is formed, it will be destroyed by volcanoes, earthquakes and other reasons.

Amber is a coniferous plant in a very hot primitive pine forest 450-1 100 million years ago. Because of the hot weather, the resin spilled from the broken or damaged branches dripped to the ground. After thousands of years, it has been petrified under the action of pressure and heat.
