Every page on https://jmtechpower.com/ shares the same top header. Next to Login / Register (or your account links) sits a small language dropdown labelled Select Language / 选择语言. It is the quick way to switch the whole site between English and Chinese.

How to switch

• Open the dropdown in the top header — the control with class language-dropdown inside .language-selector.
• Choose English or 中文. The options come from the site's language list (en → English, zh → 中文).
• Choosing one reloads the page through https://jmtechpower.com/set_language/en or https://jmtechpower.com/set_language/zh. You land back on the page you were reading (or the home page if there is no referrer).
• Nav labels, buttons and many page strings then appear in the language you picked — for example Chinese readers see 选择语言, 登录 and other translated UI copy across the site.

Good to know

• No account needed. Anyone can switch language; you do not have to log in.
• Session memory. The choice is stored in your browser session, so it sticks as you move around until the session ends.
• Not the theme picker. The colourful 🎨 button opens the theme panel (colours and look). The language dropdown only changes English versus 中文 — they sit next to each other but do different jobs.
