Thank you very much for your answers. My girlfriend and I are watching the Gregorian calendar by ourselves. The date is tentatively set as September 10. Would you please have a look?

Teachers' Day in September 10, which is quite good. Today is the thirteenth day of the eighth lunar month. You'd better find someone to do the math and see if it's good. Getting married is a big deal, so be careful, but I set the wedding date myself, and I didn't find anyone to calculate it, because if I forget it, it will be difficult to find a hotel, as long as it is a weekend, hehe.
