This rule was formulated by Alibaba to specify nicknames (English name abbreviations or nicknames) for company employees.

The specific rules are as follows:

1. Nicknames are divided into three categories, namely Chinese and English name abbreviations, Chinese and English nicknames, and company-wide public nicknames. Among them, Chinese and English nicknames refer to nicknames used by an employee within Alibaba.

2. Chinese and English name abbreviations use the first few letters of the English alphabet, and numbers are added if there are duplicate names.

3. Chinese and English nicknames use nicknames within 20 characters, and cannot use inappropriate content such as politics, religion, vulgarity, or skirting the rules.

4. Public nicknames are nicknames jointly determined by several senior employees or managers within the company. New employees can choose to use them according to their own circumstances after joining the company.

It should be noted that nicknames are a way to facilitate communication between colleagues, and are not official standard names used for document processing, dispatch work, or salary.
