7. (10 points) In the two vertical equations below, the same Chinese characters represent the same digits, and different Chinese characters represent different digits. The two and two blanks are filled with the same digits respectively: Therefore, the value of “Huayuan Tanmi” is $\qquad$
$$
\begin{array}{rcc}
2011 \\
+ \text { Shuxue Huayuan } \\
\hline \text { Wo'ai Tanmi }
\end{array}
$$
【Solution】Solution: According to the first step of the addition and subtraction vertical calculation, we have:
$$
=6
$$

Based on $0+$ 学 $=$ 爱, combined with the rule that "the same Chinese character represents the same digit, and different Chinese characters represent different digits," the result of $1+$ 花 must carry over, and 探 is still the highest digit of a four-digit number, so 探 cannot be 0. Therefore, 花 $=9$, 探 $=1$, and 爱 $=5$.

Then, $6+$ 园 must carry over.
According to the vertical addition, we know: 学 $=4$.
Since 花 $=9$,
the subtraction 习 - 花 must borrow, so 学 - 探 can only be 2.
$$
\begin{array}{r}
\text { Therefore, } \\
=2
\end{array}
$$

Since $6+$ 园 must carry over, based on the digits represented by the Chinese characters and their conditions, we can deduce:
$$
\text { 秘 }=3 \text {, 园 }=7
$$

Therefore: 数 $=6$, 我 $=8$
As shown in the figure:
Answer: "花"园探秘" is 9713
So the answer is: 9713.
