红色节点都是人, 以红框人物为条件,查询所有有关系的一级人物目前使用的是UNION拼接,还有其他方案么,求助

MATCH (a:People{name:‘何成’})-[r]-(b:People) RETURN a.name as 目标A,b.name as 名字,type® as 关系 UNION MATCH (a:People{name:‘何成’})-[r]-()-[]-(b:People) RETURN a.name as 目标A,b.name as 名字,type® as 关系 UNION MATCH (a:People{name:‘何成’})-[]-()-[r]-()-[]-(b:People) RETURN a.name as 目标A,b.name as 名字,type® as 关系
