引语的标点符号问题

“Every person is remarkable", the words President Xi said brought Chinese people a lot of warmth. 请问这句话里逗号的地方正不正确？

1. 假如后面有同位语，那样，直接引语用逗号时，它在引号里面和外面都可以，the words 是其同位语：

“Every person is remarkable,"  the words President Xi said brought Chinese people a lot of warmth.

“Every person is remarkable", the words President Xi said brought Chinese people a lot of warmth.

2. 假如后面是 President Xi said，逗号需要在引号之内：

“Every person is remarkable,"  President Xi said.

3. 直接引语内假如用句号，那样意味着这句话已经结束。下一句应大写，重新开始新的句子：

“Every person is remarkable."  The words President Xi said brought Chinese people a lot of warmth.
