9. (5 points) The following is a 3x3 grid, where the characters 【Hua, Luo, Geng, Bei, Shu, Xue, Jing, Ying, Sai】 represent nine different digits from 1 to 9, and these nine numbers meet the following three conditions:
(1) The sum of the four numbers in each "square" is equal.
(2) Hua $\times$ Hua $=$ Ying $\times$ Ying + Sai $\times$ Sai.
(3) Shu > Xue
According to the above conditions, the product of the three numbers represented by 【Hua, Bei, Sai】 is $\qquad$
【Analysis】According to the 3 conditions, classify and discuss each one by one to determine the values of Hua, Bei, and Sai, and thus obtain the product of the three numbers.

【Solution】Solution: According to the text in the figure, Hua, Luo, Geng, Bei, Shu, Xue, Jing, Ying, and Sai respectively represent nine different numbers from $1 \sim 9$,
$5^{2}=3^{2}+4^{2}$, according to condition (2), Hua is 5, Ying and Sai are 3,4 or 4,3;
(1) When Ying is 3 and Sai is 4, from condition (1) Luo + Geng $=7$, and $5+$ Luo $=3+$ Jing, it can be concluded that Luo can only be 6, Geng is 1, and Jing is 8,

So $8+$ Bei $=4+$ Xue, no solution, does not meet the requirements,
Therefore, Ying is 4, Sai is 3;
(2) Since from condition (1) Luo + Geng = 7, at this time, Luo and Geng can only be 1,6 or 6,1,
(1) When Luo is 6 and Geng is 1, from condition (1) $5+6=4+$ Jing, Bei + Jing $=3+$ Xue, at this time Jing is 7, Bei is larger than Xue
4, does not meet the requirements.
(2) When Luo is 1 and Geng is 6, from condition (1) $5+$ Bei $=6+$ Xue, Bei + Jing $=$ Xue +3, it can be concluded: Jing $=2$, Bei is larger than Xue by 1,

Also, from condition (3) Shu $>$ Xue, it can be concluded that Xue is 7, Bei is 8, Shu is 9, which meets the requirements.
Therefore, Hua is 5, Bei is 8, Sai is 3,
Thus, the product of the three numbers represented by Hua, Bei, and Sai is: $5 \times 8 \times 3=120$.
The answer is: 120.
