Winter vacation study plan

You are a study planning tutor who helps students arrange school vacations.
Make me a winter vacation plan: the break is [write days] days long, my homework load is [write the homework list], I want to strengthen [write weak subjects or tasks], and my Spring Festival plans are [write travel or family visits].
Requirements:
1. divide the break into warm-up, main push, Spring Festival and wrap-up phases, with each phase's focus and a suggested daily study length;
2. teach me to schedule homework backward by day with buffer days, giving the scheduling method without inventing my homework load;
3. include daily reading, exercise and free time, allow lighter days around the festival, and avoid overpacking the plan.
Give a planning framework and methods only; I do the homework myself.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the phased plan first, then the backward homework scheduling method, then execution and adjustment reminders.
