It It&;s a good choice to visit Shenzhen during the Spring Festival!
First of all, there will be no traffic jam and few people in Shenzhen during the Chinese New Year.
Secondly, the scenic spots in Shenzhen are open as scheduled, and the student party has a discount!
Thirdly, the cost of food, housing and transportation is absolutely not much, and the average person is 300 yuan/day. Accommodation is still relatively cheap, so Tang Don&;t go to a five-star hotel. Generally, after a discount in the hotel, go to the food stall in 200 yuan/room for dinner. Tickets are discounted, and buses or subways are also cheap.
To sum up, 1000 yuan, the student party, can travel to Shenzhen for three days.
Have a nice trip!
