Librarians and other Qingshui yamen are very relaxed and their wages are relatively stable. If it is a public institution, it may be relatively stable. If it is a private organization, it may depend on the nature of your position and how the boss of their company stipulates it. Basically, such jobs are common and there are many, but I don't think young people are suitable for those jobs. Apart from being popular and pleasant, these positions are relatively stable and there is no room for promotion.
