This means that all the income and deductions of the couple are added together, to obtain the taxable income (as mentioned above, one at the federal level and one at the cantonal level).
为了方便海外患者跨境就医，在国家卫生健康委指导下，深圳制定实施了我国首部国际医院评审认证标准——《国际医院评审认证标准（中国）》（CIHA），实现了医疗卫生领域标准从引进到输出的跨越。截至2025年底，全国已有80余家医院开展认证，12家通过认证。其中，广东、海南有8家三甲医院通过认证，均设有中医科。特别是4家港澳医疗机构获批通过，标志着我国医院评审标准成功“出海”，成为粤港澳大湾区医疗规则衔接的重要纽带。

Often people write these metrics as \(ds^2 = \sum_{i,j} g_{ij}\,dx^i\,dx^j\), where each \(dx^i\) is a covector (1-form), i.e. an element of the dual space \(T_p^*M\). For finite dimensional vectorspaces there is a canonical isomorphism between them and their dual: given the coordinate basis \(\bigl\{\frac{\partial}{\partial x^1},\dots,\frac{\partial}{\partial x^n}\bigr\}\) of \(T_pM\), there is a unique dual basis \(\{dx^1,\dots,dx^n\}\) of \(T_p^*M\) defined by \[dx^i\!\left(\frac{\partial}{\partial x^j}\right) = \delta^i{}_j.\] This extends to isomorphisms \(T_pM \to T_p^*M\). Under this identification, the bilinear form \(g_p\) on \(T_pM \times T_pM\) is represented by the symmetric tensor \(\sum_{i,j} g_{ij}\,dx^i \otimes dx^j\) acting on pairs of tangent vectors via \[\left(\sum_{i,j} g_{ij}\,dx^i\otimes dx^j\right)\!\!\left(\frac{\partial}{\partial x^k},\frac{\partial}{\partial x^l}\right) = g_{kl},\] which recovers exactly the inner products \(g_p\!\left(\frac{\partial}{\partial x^k},\frac{\partial}{\partial x^l}\right)\) from before. So both descriptions carry identical information;
