In September, 2009, on July 26th of the lunar calendar, what grade should the children of 14 attend?

Second grade. September 14 exceeded the admission requirements, so I didn't enter primary school until the next year. So the time for children born in September 2009 and 10 to enter primary school is the same. Needless to say, it's 14, even if it's 1 in September, it won't be promoted, and it won't be promoted if it is discovered. Evening is not bad for a year. Once the foundation is laid, you can go up without detours and go straight up. So don't let it go just because you are a year late. No problem.
