这句英文有错吗?while the most of children like snow but the most of adults hate it

两处错
while 引导让步句时不可以和but 连用,所以,应该说：
Most children like snow ,but most  adults hate it
或者：
While most children like snow ,most adults hate it
the most of children（adults) 要改为most children,（adults) 或者most of the children（adults)
