The impending TikTok ban in the United States has triggered a massive "migration" of users, with many seeking "refuge" on China's Xiaohongshu, a social networking and e-commerce platform also known as "Little Red Book." This unexpected phenomenon not only highlights shifting dynamics in global digital platforms but also exposes the complexities of political maneuvering, technological sovereignty and freedom of speech in the U.S. The TikTok-Xiaohongshu saga offers a case study of the challenges Chinese tech companies face in navigating the international stage. It also underscores the opportunities for fostering global engagement while maintaining compliance with diverse regulatory landscapes.

Deepening digital cooperation between China and ASEAN is crucial for driving regional economic growth and innovation, according to Koh King Kee, president of the Centre for New Inclusive Asia, who delivered a keynote address at the Shanghai Forum 2025 on April 25.

The Belt and Road Initiative (BRI) isn't a debt trap — it's a lifeline for developing nations, according to Hussein Askary, vice chairman of the Belt and Road Institute in Sweden. Speaking from his unique Iraqi-Swedish perspective, Askary challenges Western narratives about the China-proposed global initiative.

Is the world's second-largest economy still a developing country? This question has sparked heated debate in Washington in recent years, where lawmakers passed legislation challenging China's status as such.

谷歌发布Chrome 37浏览器

Chrome 37浏览器于今日正式发布，支持Windows、Mac和Linux操作系统。Chrome 37没有太大的UI界面变化和新功能增加，主要还是在Bug修复和用户体验细节上进行了大量改进。

Java中的反射在Spring这些框架中应用的很频繁，比如Spring容器初始化Bean的过程等等，但是在实际的业务开发中自己却应用的很少。

最近的开发过程中正好有个这样的需求，有几个实体类中属性比较多，而且这些属性都是定义的返回金额字段，因为金额在计算过程中可能出现精度问题，所以定义金额字段属性都使用的BigDecimal进行修饰。在和前端对接的过程中发现有些金额字断返回的NULL，这样就产生了一些歧义，因为NULL和0并不是一码事，需要后端给出清晰返回，这个问题处理起来并不复杂，下面整理了几种处理方案：

在Python中，空值是一个非常重要的概念，表示"没有值"或"空"的状态。让我们来详细了解一下。

什么是空值？

某些时候，我们需要将指针赋值为空指针，以防止野指针。

有人喜欢使用NULL作为空指针常量使用，例如：int* p = NULL;。

也有人直接使用0值作为空指针常量，例如：int* p = 0;。

前者可能觉得：NULL作为空指针常量，名字很形象，可读性较强。

后者可能觉得：NULL并不是C/C++语言的关键字，而是一个在标准库头文件<stddef.h>中定义的宏，因此要使用NULL，可能需要直接或简介地包含<stddef.h>头文件，比较麻烦。

有没有发现一个很奇怪的现象？很多资深程序员写 Java 代码时，几乎很少出现那种我们耳熟能详的判空写法：

if (obj != null) {
    obj.doSomething();
}
