shop achieved page show product category not corretly

Hi,

the original shop page shows products only, I added an woocommerce product category widget in the sidebar position, but later I delete it.
then the shop page looks weird afterwards.

It shows the shop category(Feature and mother categories) at the top firstly and then products.
when you click the mother categories, then it shows many child categories firstly and then products again
(laptop and mobile)

in short words, it looks really ugly… (below is the category view)

I think shows the category at the top is OK, so I hope to make below amended
( or maybe make it back to normal firstly and then make amends)

1. don’t show the numbers of products
2. what if I want to show the texts of categories at the top + product of Featured and products of Hot/new only
3. how to set numbers of display products at one page ( default is 16 items per page,Max 48 per page) , I want to display more.
