The symmetry for two-dimensional (2D) dispersionless Toda lattice hierarchy (dTLH) is firstly derived. and then the 2D dTLH is extended based on the symmetry constraint. The commutativity of two different flows for this new hierarchy is shown. which leads to the 2D dToda lattice equation with self-consistent sources (dTLESCSs) together with its conservation equation. https://hollandscountryclothinges.shop/product-category/game-copyright/
