重命名Woo-commerce产品选项卡

Question

I have used this to rename the description tab into "More Information"

but it will not work, what do I wrong?

I use Woocommerce Version 3.4.3 with Booking extension

    <?php
  add_filter( 'woocommerce_product_tabs', 'woo_customize_tabs', 100, 1 
 );
 function woo_customize_tabs( $tabs ) {

 unset($tabs['reviews']);    // Remove the reviews tab

 $tabs['description']['title'] = __( 'More Information' ); // Rename the 
 description tab

 return $tabs;
 }
