Which is better, Taobao World or the world's online merchants?

Both will do. Taobao Tianxia and Tianxia.com are both outsourcing companies of Ali. It is a company jointly funded by Alibaba and Zhejiang Newspaper Group, which is considered as a semi-subsidiary. "Taobao Tianxia" and "Tianxia Online Merchants" are part of the e-commerce content ecology of service companies, but after more than ten years, the effect has declined.
