Long Yuan periodical is actually a place to provide paper materials. At present, the well-known databases in China include HowNet database, Wanfang database and VIP database. , similar to foreign SCI database or EI database. If the article you sent can't be found in the above database, it just means that the periodical paper you sent has not been searched by the above database. As long as the periodical is a regular periodical, there is no problem. I suggest you take a look at Baidu: General Journal Academic Center, which has many video tutorials and some paper writing.
