#include <bits/stdc++.h>
using namespace std;
int main()

    if (s == "I had finished my homework!")
        cout << "Good Child!";
    else if (s == "I went to Guangzhou!")
        cout << "You have a good time for Xiaomawang Coding Bootcamp!";
    else if (s == "I'm not happy!")
        cout << "You can do exercise.";
    else
        cout << "Haha,\\QAQ/~.";
    return 0;
