I'm not sure what you mean by 南阳伦敦金、Could you please provide more context or clarify your question?

If you're referring to London Gold in Nanyang, I found that Nanyang is a city in Henan Province, China, and there is a gold market in Nanyang where London gold (also known as international gold or spot gold) is traded.

London gold refers to gold traded on the London Bullion Market, which is one of the largest and most wellestablished gold markets in the world、The price of London gold is often used as a benchmark for gold prices globally.
