day method does not work after configuring the locale

[cannot-hero]

Describe the bug
I use dayjs.locale('zh-cn'), but dayjs('2024-11-24').day(1) return 2024-11-25
Expected behavior
dayjs.locale('zh-cn')
dayjs('2024-11-24').day(1) return '2024-11-18'
Information

• Day.js Version 1.11.8
• OS: windows
• Browser chrome
• Time zone: [e.g. GMT-08:00

Same here. locale seems to work with all locales but 'zh-cn'.

Sorry, I was to quick with my reply. I didn't imported the locale first, thats why setting the locale first. @cannot-hero mayby this fixes it for you too: import 'dayjs/locale/zh';

@baddel73 thanks for your reply, but this still doesn't work for me, to solve this problem, i use
function getFirstDayOfWeek(date, formatType = 'YYYY-MM-DD') { return dayjs(date).startOf('week').format(formatType) }
in this case, after use dayjs.locale('zh-cn'), the start of week will be Monday. This isn't an elegant approach, but it works.
