Recently, everyone has heard the news about the economic recovery, right? After three years of mask testing, all walks of life are experiencing recovery in the first half of 2023, and there are endless discussions about the workplace.
How is the employment environment now? Which industries are more promising? When looking for a job, do you choose first-tier cities or return to second- and third-tier cities? ... Regarding this series of workplace topics, the "Talent Flow and Salary Trend Report for the First Half of 2023" recently released by Liepin lists a lot of data about the current talent market trends and salary situation, which may be useful to both job seekers and companies. Has a certain reference value. Let’s take a look at the report content.
Popular cities and popular industries are still the first choice for employment
It is the wish of most working people to choose a city that they like or have good development, and then find a decent job. Choosing which city to develop in is largely related to your expectations for work. For example, if you want a higher salary, first-tier and new first-tier cities will become everyone's first choice.
In a report released by Liepin, the city with the highest average monthly recruitment salary in the first half of 2023 is Beijing (18,976 yuan), followed by Shanghai (18,132 yuan) and Shenzhen (17,784 yuan). These three cities are also the top three for talent delivery in the first half of the year. name. Overall, recruitment salaries are still higher in first-tier cities, but recruitment salaries in new first-tier cities such as Hangzhou and Nanjing are also very impressive. 
△ Source recruitment, such as intrusion and deletion
Data in the report shows that employment wages in major cities have increased significantly: comparing the salary increases in first-tier and new first-tier cities in the first half of 2023 and the first half of 2018, Shanghai has the highest salary increase, reaching 29.6%, and Beijing has the highest salary increase of 27.48%. The second largest increase. And judging from the salary situation of talents with different educational backgrounds, Beijing, Shanghai, and Shenzhen have the highest average salaries regardless of associate degree, bachelor's degree, master's degree, or doctorate.
The report data also shows that although there have been professionals who have "escaped" from Beijing, Shanghai, Guangzhou and Shenzhen in the past three years due to reasons such as living costs, 39.2% of them will choose to return to first-tier cities. The average time between re-delivery to first-tier cities is about 20 months, and the factor that most affects the employment/settlement of workers is the city's salary level.
These data undoubtedly prove that employment in first-tier and new first-tier cities is more competitive, and they are also popular cities favored by professionals.
△ Source recruitment, such as intrusion and deletion
After talking about cities, let’s look at industry trends. When the surveyed professionals were asked which industries they most wanted to enter when looking for a job? The report showed that IT, Internet, and games ranked first with 34.3%; electronics, communications, and semiconductors ranked second with 25.7%.
△ Source recruitment, such as intrusion and deletion
There is no doubt that the IT, Internet, and gaming industries are still the favorites of working professionals with high salaries and good development prospects. But in the workplace, high salary generally means spending more energy and time. The overtime situation that everyone is more concerned about is also reflected in the report: among the surveyed workers, those with a monthly salary of 10,000-20,000 yuan most often work overtime, accounting for 60.5%; followed by those with a monthly salary of 8,000-10,000 yuan, who often work overtime The proportion is 40.2%. The proportion of workers with a monthly salary of 5,000-8,000 yuan and those with a monthly salary of less than 5,000 yuan who often work overtime is similar, both at around 40%. People with a monthly salary of more than 20,000 yuan have the lowest proportion of people who often work overtime, accounting for only 19.0%.
From this set of data, higher salary does not mean more overtime work, but a monthly salary of 20,000 is a watershed. In addition, in order to make money, the data also shows that nearly 30% of working people have the idea of setting up stalls or opening stores, and the younger they are, the more people plan to set up stalls or open stores. Among them, the post-00 generation has the highest proportion of these plans, reaching 62.5 %, followed by those born in 1995, accounting for 40.7%, and those born in the 1970s, accounting for only 20.8%, accounting for the smallest proportion.
After reading Liepin’s “Talent Flow and Salary Trend Report for the First Half of 2023”, what do you want to say? Welcome to discuss in the comment area.
As the economy picks up, why do people still say it’s difficult to find a job?
The economy is recovering, wages are rising, and the job market is starting to pick up, but why do so many people still complain that it’s hard to find a job? Perhaps as Li Qiang, executive vice president of Zhaopin Recruitment Group, said: The biggest problem in employment is not that there are no job opportunities in the market, but that the job requirements are different. Job seekers must find a good job instead of looking for a job.
As the recruitment survey results say, when looking for a job, city, salary, whether to work overtime, etc. are all key issues that everyone considers when looking for a job. As more and more people enter the workplace, good job opportunities are always rare. And good jobs often mean high demands.
Take the popular position of Java development engineer as an example. According to third-party platform statistics, the national recruitment volume is over 100,000. However, if you click on the job requirements, you will find that companies generally require mid-to-senior development engineers with 2-3 years of work experience. 
△ Source: Zhiyouji, such as intrusion and deletion
According to the graduates of Dark Horse, good job opportunities nowadays often mean that you must have: outstanding professional skills, rich experience, a beautiful resume, excellent interview performance, strong work ability, and solving practical problems. ability……
It is not easy to gather the above skills together. This has resulted in a situation where although there are many jobs available in the current job market, there are not enough talents who can meet the company's requirements, making many people find it difficult to find a job.
Know the problem and find the solution to solve it
Just because a good job is hard to find doesn’t mean there are no opportunities. Opportunities always come to those who are prepared.

If you want to be an excellent front-end engineer, you first need to learn the three core basic skills of HTML, CSS, and JavaScript. After learning these, you can make a static website. At this time, the website cannot interact with users and allow users to use it. You need to learn more. Ajax can further request the back-end interface and realize data interaction between the front and back ends. At this time, the website can basically interact and use with users.
Of course, we not only need to learn PC-side development, but also mobile-side development. We also need to learn mobile-side technologies, such as: rem, Boostrap, media query, etc. At this time, PC and mobile websites can basically be developed, but issues such as website development efficiency and performance optimization also need to be considered, so there is more to learn, such as: front-end building tool webpack, front-end framework Vue or React, etc. etc., all need to be mastered by front-end engineers.
Most of the current website development is developed in the front-end and back-end separation model, but it does not mean that front-end development does not require knowledge of the back-end. Front-end engineers also need to master Node.js skills. Node.js is already a core essential skill in many companies.
Internet technology is developing faster and faster. If you want to become a front-end engineer, you must learn technology in an organized and planned way to gain a firm foothold in the industry. If you are determined to learn front-end, I hope the above learning roadmap can stimulate your interest in learning front-end. More importantly, you can gain knowledge from it and make your progress on the front-end advancement smoother and smoother!
