There exists a great deal of concrete evidence in favor of the exotic four-quark nature of light scalars. At the same time, the further expansion of the area of the q2q2 model validity for light scalars on ever new processes seems extremely interesting and important. We analyze the BESIII data on the decay J/ψ → γπ0π0 and show that the results of this high-statistics experiment can be interpreted in favor of the four-quark nature of light scalar mesons f0(980) and f0 (500).
