Tourism and market regulators could develop model contracts for hiking companion services to provide standardized references and guidance for both tourists and service providers.

旅游和市场监管机构可以为徒步搭子服务制定示范合同，为游客和服务提供者提供标准化的参考和指导。

As well as modelling contracts and book deals, each child's name is trademarked which means only the Beckham's can use their names on products.

像模特签约和书籍签售一样，每个孩子的名字都被注册为商标——这意味着只有贝克汉姆一家可以把他们的名字用在商品上。
