I need to make a BST. However, each node is essentially the root for a binary search tree that can be added to that. The example is:

You have several shoe shops stored in a BST but each shop carries different shoes

Once the shop is made, I don't understand how to use that shop root (node) and make a new tree under each shop that will hold the shoe name and a left and right pointer connecting other shoes. Would I need to make another insert function? I know I'll have to free memory, but for now I am trying to figure out the insertion of the other nodes.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct mainNode 
 char* name;// Shop Name
 struct mainNode* left;
 struct mainNode* right;
 struct regNode* root; // Pointer To Sub Node
 MainTreeNode;

typedef struct regNode
 char * name;// Shoe Name
 struct regNode *left;
 struct regNode *right;
 regNode;

MainTreeNode* insert(MainTreeNode* root, char* name);

void inOrder(MainTreeNode* root);

int main() 

 // Create tree
 MainTreeNode* MainTreeRoot = NULL;

 MainTreeRoot = insert(MainTreeRoot ,"nike");
 MainTreeRoot = insert(MainTreeRoot, "adidas");
 MainTreeRoot = insert(MainTreeRoot, "underArmour");
 MainTreeRoot = insert(MainTreeRoot, "rebbok");

 inOrder(MainTreeRoot);
 printf("n");

 return 0;



// Inserts a new node into the tree rooted at root with data set to value.
// and returns a pointer to the root of the resulting tree.

MainTreeNode* insert(MainTreeNode* root,char* name) 

 // Inserting into an empty tree.
 if (root == NULL) 
 MainTreeNode* temp = malloc(sizeof(MainTreeNode));
 temp->name = name;
 temp->left = NULL;
 temp->right = NULL;
 temp->root = NULL;
 return temp;
 

 // Go left
 if (strcmp(name,root->name) < 0)
 root->left = insert(root->left,name);

 // Go right
 else
 root->right = insert(root->right, name);

 // Must return the root of this tree
 return root;


void inOrder(MainTreeNode* root)
 if (root != NULL) 
 inOrder(root->left);
 printf("%s n", root->name);
 inOrder(root->right);
