This is not an answer, this is a message to @Gjergji Zaimi. Thank You very much. (And thank to dear  Wolfgang very much). Your answer is true with this version.

Could You see my comment to You and Wolfgang. I say that when $m=n$ the inequality 1 is [A Muirhead Like Inequality](https://mathoverflow.net/questions/303013/a-muirhead-like-inequality). The inequality 2 is [A Muirhead](https://www.cut-the-knot.org/arithmetic/algebra/MuirheadInequality.shtml)

I see detail my question again (with Wolfgang help). I think this inequality is not fomulate true with my ideas, so may I re-fomulate my ideas again. (Because I say that when $m=n$ the inequality 1 is [A Muirhead Like Inequality](https://mathoverflow.net/questions/303013/a-muirhead-like-inequality). The inequality 2 is [A Muirhead](https://www.cut-the-knot.org/arithmetic/algebra/MuirheadInequality.shtml)). May I refomulate my ideas as follows: 


>**Inequality 1:** Let $n>2$ and $1 \le m \le n$ be integers. Let $x_1, \dots, x_n$ and $y_1,\dots, y_n$ be nonnegative real numbers such that $(x_1,\dots, x_n)$ [majorizes](https://en.wikipedia.org/wiki/Majorization) $(y_1,\dots, y_n)$. Then for all reals $0 \leq a_1, a_2,\cdots,a_n \leq 1$, 

>$$\sum\limits_{sym}\left(  \sum\limits_{sym} x_{i_1}^{a_{p_1}} \cdots x_{i_m}^{a_{p_m}} \right) \leq \sum\limits_{sym}\left(  \sum\limits_{sym} y_{i_1}^{a_{p_1}} \cdots y_{i_m}^{a_{p_m}} \right) $$

* When $m=n$ this inequality is [A Muirhead Like Inequality](https://mathoverflow.net/questions/303013/a-muirhead-like-inequality)

>**Inequality 2:** Let $n>2$ and $1 \le m \le n$ be integers. Let $x_1, \dots, x_n$ and $y_1,\dots, y_n$ be nonnegative real numbers such that $(x_1,\dots, x_n)$ [majorizes](https://en.wikipedia.org/wiki/Majorization) $(y_1,\dots, y_n)$. Then for all reals $ a_1, a_2,\dots,a_n \geq 0$, 

> $$\sum\limits_{sym}\left(  \sum\limits_{sym} a_{i_1}^{x_{p_1}} \cdots a_{i_m}^{x_{p_m}} \right) \geq \sum\limits_{sym}\left(  \sum\limits_{sym} a_{i_1}^{y_{p_1}} \cdots a_{i_m}^{y_{p_m}} \right)$$
