摘要：
The data sample of 1.3 x 10(9) J/psi events accumulated at BESIII provides us with a clean environment to study the decay of the eta'. In this proceeding, several recent results are reported, including the observation of the doubly radiative decay eta'-gamma gamma pi(0), amplitude analysis of the decays eta'->pi(+)pi(-)pi(0) and pi(0)pi(0)pi(0), the observation of the Dalitz decay eta'-gamma e(+)e(-), and search for the weak decay eta'-> K-+/-pi(-/+).
