First of all, we need to know what the research status at home and abroad is. In fact, it is generally the research status of a research object at home and abroad, which can be the research of relevant departments at the national level or the research of authoritative scholars.

Therefore, there are two ways to clarify the research status at home and abroad, either from the research of the relevant departments on the research object or from the research of scholars on the relevant research status.

Generally speaking, the current research situation at home and abroad requires you to read a lot of literature, and then summarize the main viewpoints of scholars. Here is a hint for you, which can be seen directly from the abstract of an article. In this case, even if you don't read the article completely, you can know the main points of the article.

There is another way to extract directly from the master's thesis. You can find some master's theses with the same topic or keywords. We can extract the research status at home and abroad and change this sentence into our own meaning. This is also a writing method.

However, when you note the quotation, you must find the most fundamental article, not the master's thesis you are referring to. Where can I find the literature? In Chinese, you can look directly at Baidu Academic or HowNet, mainly at the abstract of an article, because the main points are in the abstract.

In English, as mentioned before, a large number of foreign documents can be found by searching the keywords of Google Academic. It should be noted here that if you look for keywords in foreign literature, you must translate them into English. If it is in Chinese, there is no way to identify it. Then you just need to translate the relevant English documents into Chinese and summarize them.
