Final answer:
The provided options in the question do not directly correspond with any group that was not considered ghosts by the Chinese. History shows that the Portuguese, given their trading rights in Macio, held a distinct position compared to other Europeans in the Qing dynasty. Similarly, Korea, being a tributary state, might have been on better terms, but the term ghosts generally applied more broadly.
Step-by-step explanation:
The question of who were the only foreigners not considered ghosts by the Chinese pertains to historical perceptions during distinct periods of Chinese relations with foreign entities. Considering the historical references, it can be deduced that none of the options provided clearly applies to those who were not considered ghosts by the traditional Chinese worldview. However, looking at the interactions during the Qing dynasty, it seems that the Portuguese might have been viewed differently since they were allowed to reside in Macao and conduct trade, albeit under strict regulations. This accommodation suggests some level of acceptance beyond that of the common foreigner who was typically seen with suspicion and resentment. Thus, in dealing with the Qing dynasty, the Portuguese held a unique position compared to other European foreigners.Additionally, it's important to note that Chinese treatment of foreigners varied across dynasties and epochs. Tributary states nearer to China, like Korea, often presented at the imperial court and might have had somewhat better acceptance, but the question specifically refers to those not seen as ghosts, which is a term often used to describe a broader exclusion or else disdain. Therefore, while the question doesn't have a definitive answer among the provided options, some historical contexts can offer insights into different layers of foreign acceptance.
