Is the primary school placement in Hefei random?

Yes The placement of Hefei primary school is demonstrated by live computer. Director Liu of the Academic Affairs Office of the Primary School Department introduced that the freshmen's data, taking into account the two factors of basically equal class size and balanced male-female ratio, were randomly put on the spot. Secondly, all class teachers draw lots to determine the class, and print out the final class list under the supervision of parents, and all the teachers present and parents sign for confirmation.
