• 答案： • Worried Jerry，
• You needn't worry too much about that. It's a good idea to travel around in the winter holiday. You should relax after a long period of study; besides, you may pick up lots of useful knowledge while travelling.
• In my opinion, you should tell your parents about it first. They will offer you some suggestions. If they don't give some money to you, it doesn't matter. You can do some parttime jobs to make money. It's very interesting and meaningful! What's more, you can also invite your friends to go with you. Take good care of yourself. As long as you are willing to prepare well, everything will be OK!
