Make a measurement of where the trees come through the flooring and cut around the trunks with a jigsaw, leaving 1" to 2" around. Once your deck boards have been cut to accommodate the trunks of your tree, it's time to screw them into place. Use a ladder to hoist yourself up onto the platform and start screwing down with a drill. Leave a slight 1/4" or 1/2" distance between each floorboard. Add covering and verticals to the platform to make a rectangle. Now an awkward part that formerly jutted out of the platform has been turned into a handy-dandy entrance. Nail the two 2x4 (they should be at least 4 feet high) together, and then screw them to the platform at each corner. Use 2x4s as well, and if you want, mitre the edges of the handrails. Then, nail them down to the uprights. Next, screw the handrails into one another through their mitered corners. Nail any available woods — planks or plywood work fine — flush into the bottom of the platform. Then nail them into the railing at the top so that they form an effective fence. Use whatever you want for siding. You can successfully use meshed-together rope if you want, as long as little kiddies cannot slip through. Safety should be the first priority, especially when you're dealing with small children.

How would you rephrase that briefly using Chinese?
找出树屋平台上你需要切除的部位，让平台和树木符合设计。 在每个板的末端拧两个螺丝，最短使用0.10米长的螺丝。 在主要支撑结构处搭建一个入口。 在每个角落使用两个2x4规格木板，做立柱的扶手。 连接扶手立柱。 在平台的底部和扶手的底部加壁板。
