The foreign merchants were indeed the best information spreaders. They traveled all over the loucheng world and often exchanged information with their peers. It could be said that they were " well-informed.
Of course, it was unknown how much useful information was in this so-called " knowledgeable ".
Therefore, it was a good idea for the foreign woman in the pub to ask Tang Zhen about the foreign merchants. However, whether it would work or not would depend on the situation.
Tang Zhen didn't have much contact with the foreign merchants and had never bought information from them. He didn't even know that such a situation existed.
These foreign merchants were indeed shrewd. They had actually found such a way to make money. They had really learned and applied the saying " knowledge is wealth "
If there was a lot of gossip and business was good, it was not impossible to make a living purely on this.
