In plain English

This repository is a collection of Java interview questions, backend development fundamentals, and practical work summaries written in Chinese. It is aimed at software developers who are preparing for technical interviews at large technology companies in China. The author describes it as a personal study and experience-sharing project assembled over time, with the goal of helping other developers land their target job offers. The content is organized into several areas. One section covers practical lessons learned on the job, with articles on topics such as database replication delays, keeping cache and database data in sync, logging best practices, common code mistakes and how to avoid them, interface performance optimization, MySQL table design rules, and secure storage of user passwords. Another section offers a collection of original interview questions spanning more than 500 pages, linked through a Chinese social media platform. The repository itself does not contain code files. Instead, it is a curated list of links pointing to articles published on the author's WeChat public account, a popular platform in China for sharing technical writing. Readers follow the links to read the full articles. This is a Chinese-language resource. Most of the content is not accessible or readable without understanding Chinese. It is primarily useful to Chinese-speaking developers who are studying backend engineering topics or preparing for interviews at Chinese technology companies.
