神经病人思维广弱智儿童欢乐多
[shén jīng bìng rén sī wéi guăng ruò zhì ér tóng huān lè duō]
In English this says, 'Mentally-ill people have wide thoughts; foolish kids find much joy'. While appearing nonsensical, this may be used satirically, pointing to differences in thought processes and levels of happiness among different groups.
