tag. We need to preserve HTML structure, translate naturally, keep proper nouns like Zelenskiy (probably keep as Zelenskiy or 泽连斯基? The instruction says keep proper nouns in original form, so keep "Zelenskiy" as is, but maybe transliterate? It says "Keep proper nouns (names, company names) in original form", so we should keep "Zelenskiy" as is, not translate to 泽连斯基. Similarly, "Shahed" is a name, keep as "Shahed". "Russia" and "Ukraine" are country names, but we might translate? The instruction says keep proper nouns, but country names are typically translated. However, "Russia" and "Ukraine" are proper nouns, but they have standard translations: 俄罗斯 and 乌克兰. The instruction says "Keep proper nouns (names, company names) in original form" - that likely refers to personal names and company names, not country names. But to be safe, we should follow standard translation for country names. Also "Zelenskiy" is a person's name, so keep as is. "Shahed" is a drone model, keep as is. "Iranian-designed" - we can translate "Iranian" as 伊朗的. So we need to translate the content into Chinese, keeping the HTML structure.
We'll produce a JSON object. The title: "Russia Launches 35 Missiles, 185 Drones in Attack on Ukraine, Zelenskiy Says" -> translate to Chinese. We can say: "泽连斯基称俄罗斯在袭击乌克兰时发射35枚导弹和185架无人机" but we need to keep "Zelenskiy" as is? Actually, the name is "Zelenskiy" - we could keep it as "Zelenskiy" but in Chinese text, it's common to transliterate. However, the instruction says keep proper nouns in original form. So we should keep "Zelenskiy" as is. But the title has "Zelenskiy Says" - we can say "Zelenskiy表示" or "Zelenskiy称". So title: "俄罗斯在袭击乌克兰时发射35枚导弹和185架无人机，Zelenskiy称" but that's a bit awkward. Better: "Zelenskiy称俄罗斯在袭击乌克兰时发射35枚导弹和185架无人机" or "俄罗斯发射35枚导弹和185架无人机袭击乌克兰，Zelenskiy称". We'll choose a natural translation.
For content, we'll translate each paragraph.
We'll also translate the meta description.
Let's do it step by step.
We need to output valid JSON. So we'll escape double quotes if needed.
Let's write the translation.
Title: "俄罗斯发射35枚导弹和185架无人机袭击乌克兰，Zelenskiy称" (but we might want to keep the structure: "Russia Launches ... in Attack on Ukraine, Zelenskiy Says" -> "Zelenskiy称俄罗斯在袭击乌克兰时发射35枚导弹和185架无人机" - that's fine.
Content: We'll translate the article.
First paragraph: "Russia fired 35 missiles and 185 drones at Ukraine in a large-scale overnight assault, President Volodymyr Zelenskiy said. The attack combined both cruise and ballistic missiles with a swarm of unmanned aerial vehicles, marking one of the heavier barrages in recent weeks."
We'll translate: "俄罗斯在一场大规模夜间袭击中向乌克兰发射了35枚导弹和185架无人机，总统Volodymyr Zelenskiy表示。此次袭击结合了巡航导弹和弹道导弹以及大量无人机，是最近几周最猛烈的攻击之一。"
But we should keep "Volodymyr Zelenskiy" as is? The instruction says keep proper nouns in original form, so we keep "Volodymyr Zelenskiy" as is. But in Chinese, we might put it as "Volodymyr Zelenskiy" without translation. We'll keep it.
Also "cruise and ballistic missiles" -> "巡航导弹和弹道导弹", "unmanned aerial vehicles" -> "无人机", "barrages" -> "攻击" or "齐射".
We'll try to be natural.
Second paragraph: "Zelenskiy disclosed the numbers in a public statement, though he did not specify which regions were targeted or how many projectiles were intercepted. Ukrainian air defense units have been under severe strain as Russia increasingly uses mixed salvos to overwhelm defenses. The president did not provide an immediate casualty count or damage assessment."
Translation: "Zelenskiy在一份公开声明中透露了这些数字，但没有具体说明哪些地区成为目标，或有多少导弹被拦截。由于俄罗斯越来越多地使用混合齐射来突破防御，乌克兰的防空部队承受着巨大压力。总统没有立即提供伤亡人数或损失评估。"
Third paragraph: "The 185 drones represent a significant uptick in the use of unmanned systems. Russia has been manufacturing and deploying large numbers of Iranian-designed Shahed drones, often launching them in waves to exhaust Ukrainian air defense ammunition. The 35 missiles add a heavier punch, likely aimed at critical infrastructure or military sites."
Translation: "185架无人机标志着无人系统使用量的显著增加。俄罗斯一直在制造和部署大量伊朗设计的Shahed无人机，经常成波次发射以耗尽乌克兰防空弹药。35枚导弹则更具破坏力，可能瞄准关键基础设施或军事目标。"
Fourth paragraph: "This is not an isolated incident. Russia has been conducting near-daily strikes on Ukrainian energy grids, transport hubs, and residential areas since the fall. The goal appears to be to degrade Ukraine's ability to sustain its war effort and to pressure the civilian population as winter sets in. Ukraine has repeatedly called for more Western air defense systems to counter the threat."
Translation: "这不是孤立事件。自秋季以来，俄罗斯几乎每天对乌克兰的能源网、交通枢纽和居民区发动袭击。其目标似乎是削弱乌克兰维持战争努力的能力，并在冬季来临之际向平民施压。乌克兰一再呼吁西方提供更多防空系统来应对这一威胁。"
Fifth paragraph: "Zelenskiy's statement did not include details on the success of the attack or the response. Ukrainian officials often release interception figures and damage reports hours after an assault, once the all-clear is sounded and emergency crews have surveyed the scene."
Translation: "Zelenskiy的声明没有包括袭击成功或应对的细节。乌克兰官员通常在袭击数小时后发布拦截数据和损失报告，此时警报解除，应急人员已完成现场勘察。"
Now we need to wrap in tags. The original content had and
