How to arrange a one-day tour in Shenzhen?

It is best to go to Lianhua Mountain. You can fly a kite and bring some sandwiches and milk to prepare for the picnic. . .

Oh, bring: kite (essential), basket (for picnic), picnic blanket (needless to say), sports drink (to quench thirst and replenish energy), cross-country bike (riding in the park if possible), hat (sun protection), sunscreen (sun protection) and towel (wiping sweat). . . . . .

Get ready, look at the weather forecast, don't go in rainy days, choose a suitable temperature, thank you.
