Answer 1

1. Create a Websites and it's relevant Store and StoreView from Admin > Stores > All Stores

2. Go to Stores > Configuration, Select website which you have created. Then Go to Web and change both Base URLs & Base URLs (Secure)

   For example : e.g. Base URL: xyz.com (Main website url keep as it is) Base Link URL: {{unsecure_base_url}}ch/

   Here, ch is a sub directory folder which needs to create under your magento root folder

3. Create a sub directory folder, then copy index.php & .htaccess from root

4. Open index.php replace everything with the code bellow:

   require realpath(__DIR__) . '/../app/bootstrap.php';
   $params = $_SERVER;
   $params[\Magento\Store\Model\StoreManager::PARAM_RUN_CODE] = 'ch_website'; 
   $params[\Magento\Store\Model\StoreManager::PARAM_RUN_TYPE] = 'website'; 
   $bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $params);
   $app = $bootstrap->createApplication('Magento\Framework\App\Http');
   $bootstrap->run($app);
   

   ch_website is a website code.
