英文摘要：

By the invariant subspace method, the Euler equations for Chaplygin gas are reduced to finite-dimensional dynamical systems of first-order ordinary differential equations. Many interesting exact solutions, including finite-time blowup solution, global solution and time-periodic solution, are obtained. The unusual blowup interfaces of some solutions are described.
