If $m_{0},m_{1},\dots,m_{r}$ are positive integers with $(m_{i},m_{j})=1$ for $i\neq j$, prove that exists consecutive integers $s,s+1,\dots,s+i$ such that $m_{i}|s+i$ for all $1\leq i \leq r$.

I really don't know how to approach to this problem. Any tips?

We want the solution to the following system. Since $\gcd(m_i,m_j)=1$ so we can apply Chinese Remainder Theorem to guarantee the existence of a solution. \begin{align*} s & \equiv 0 \pmod{m_0}\\ s & \equiv -1 \pmod{m_1}\\ s & \equiv -2 \pmod{m_2}\\ \vdots & \equiv \vdots\\ s & \equiv -r \pmod{m_r} \end{align*}
