What mail box chinese use the most

In China, the most commonly used mailbox is the "red box" or "" (hóng huò), which is a bright red mailbox installed by the China Post (Zhōngguó Yóu Bìng) for collecting mail and packages. These red boxes are ubiquitous in urban and rural areas, and are often found in public spaces such as streets, alleys, and outside residential buildings.

The red box is a iconic symbol of China's postal service and has been in use since the 1950s. It's designed to be easy to use, with a simple slot for depositing mail and a clear indication of the mailbox's capacity. The red color is also a distinctive feature, making it easy to spot from a distance.

In addition to the red box, China Post also offers other types of mailboxes, including:

  1. Blue box (): These are larger mailboxes used for collecting larger packages and parcels.
  2. Green box (): These are used for collecting mail and packages in rural areas.
  3. Electronic mailbox (): These are digital mailboxes that allow users to receive and manage their mail online.

Overall, the red box remains the most widely used and recognizable mailbox in China, and is an important part of the country's postal infrastructure.
