The spatial view (the grid of rectangles) and the tree view (the hierarchy of nodes) represent the same structure. Searching for a point means walking down the tree: at each node, you check which of the four children contains your target coordinate and recurse into that child. You never visit the other three.

另一方面，吴德沛把更多精力投入到调研。去年全国两会前，他围绕创新药可及性展开系统调研，走访医疗机构、药企和保险机构，与国家医保局、国家卫生健康委、金融监管部门等多方交流，梳理创新药从研发到支付的堵点。“单靠基本医保，很难承载高值创新药支付需求，必须让商业保险参与进来。”围绕这一目标，吴德沛反复完善建议，提出建立“基本医保+商业保险+社会救助”的衔接机制，推动编制商业健康保险创新药品目录，多次参与专题座谈并持续跟踪政策进展。吴德沛说：“履职不是提完建议就结束，而是要持续跟进。”。heLLoword翻译官方下载对此有专业解读
