Introduction
With the rapid development of the economy of the times, Chinese youth, as the backbone of the society, are quick-thinking, skilled and talented. They have high acceptance of knowledge, strong creativity and their own distinctive personal characteristics [1]. In the process of social interaction, the transmission and expression of knowledge is influenced by the interaction between people. Knowledge hiding, as the opposite side of knowledge sharing, was proposed by Connelly in 2012. It means that when others ask questions about relevant knowledge and need help, they choose to turn a blind eye or deliberately hide it [2]. Research shows that knowledge hiding will form ' information barriers ', which is not conducive to personal development and growth [3].Personality traits are the psychological characteristics of individual behavior stability, with individual differences. It mainly includes five factors: neuroticism, conscientiousness, agreeableness, openness, extraversion [4]. Studies have shown that extroverts are more impulsive to communicate and share with others [2].Therefore, this study investigated the correlation between knowledge hiding behavior and personality traits of young people in a community in Xi 'an, aiming to provide a reference for the mental health of knowledge hiding and personality traits of young people in a community in Xi 'an.

The scale has 12 items and 3 dimensions, which are deaf-mute, avoidance and rationalization. A 5-point Likert scale was used, with scores ranging from 12 to 60, the higher the score, the higher the level of knowledge hiding. The overall Cronbach's a for this scale was 0.913. The Cronbach 's α coefficients of the three dimensions were 0.777,0.750 and 0.814, respectively.

A total of 220 questionnaires were distributed in this study, and 220 were valid, with an effective rate of 100 %.

Statistical methods
The data were statistically analyzed using SPSS25.0.expressed as mean ± standard deviation, and the count data were described by frequency and composition ratio.one-way analysis of variance using independent samples t-test or ANOVA. Correlation analysis was performed by Pearson correlation analysis. Significant differences were indicated by P<0.05. Table 1 shows that the scores of knowledge hiding behavior of young people in a community of Xi'an with gender and education level are statistically significant (P<0.05). Table 1 shows that the scores of personality traits of young people in a community in Xi'an with different gender, age, education level, marital status, monthly income and place of residence were not statistically significant (P>0.05).

The status quo of knowledge hiding level of young people in a community in Xi 'an
In this study, the score of knowledge hiding level of young people in a community in Xi'an was (2.63±0.93), which was at a medium level. The results were similar to those of Zhang Luyao et al [9] [(2.73±0.74)]. It shows that the knowledge hiding level of young people in a community in Xi 'an is high, and the score of rationalization knowledge hiding dimension is the highest. The reason may be that the young people have complex interpersonal relationships, a large age span, different ways of thinking, and different abilities to deal with problems [10]. The second is the escape knowledge hiding dimension, and the lowest score is the deaf-mute knowledge hiding dimension. Considering the possible reasons and the rapid development of social economy, people can query relevant information and share relevant knowledge through the network platform [11]. Therefore, young people should reduce knowledge hiding behavior by establishing good reputation.

The status quo of personality traits of young people in a community in Xi 'an
In this study, the scores of neurotic personality, conscientiousness personality, agreeableness personality, openness personality and extroversion personality of young people in a community in Xi'an were (21.56±5.37), (26.47±5.33), (26.75±4.77), (26.27±5.84) and (26.43±5.71), respectively. The score of agreeableness personality was the highest, while the score of neuroticism personality was the lowest, which was similar to the results of Liu Yuying et al [12]. The analysis was originally likely to be related to the work pressure, heavy burden of life, mutual respect and help of young people, while some work needs to control their emotions and be highly focused. In the face of emergencies at work, good emotions can reduce the occurrence of adverse events [13][14]. Therefore, young people should stabilize their emotions and reduce bad conflicts.

Influencing factors of knowledge hiding level of young people in a community in Xi 'an
The results of single factor analysis showed that gender and education level were the influencing factors of knowledge hiding level of young people in a community in Xi 'an. Among them, the knowledge hiding level of men is higher than that of women, which is inconsistent with the research results of Zhang Luyao et al [9]. The reason may be that the professional technology between nursing postgraduates is stronger and the confidentiality is higher. In this study, the occupational range of young people in a community in Xi 'an is different and the comparability is small. At the same time, the proportion of men and women in the young and middle-aged population of the society is not coordinated, the competitive pressure is high, and the cost of raising a family for men is higher [15]. In this study, the knowledge hiding level score of the junior high school education group was the highest (42.17±6.71), and the knowledge hiding level score of the undergraduate education group was the lowest (29.00±10.22). The results of and Pan Wei [16] are inconsistent, and the reason may be related to the low level of education and insufficient learning opportunities among young people [17].

Correlation analysis between knowledge hiding behavior and different personality traits of young people in a community in Xi 'an
In this study, knowledge hiding behavior is positively correlated with neurotic personality traits. The reason may be that the higher the level of individual neurotic personality, the greater the negative emotions generated, affecting interpersonal communication, and the desire of others to share knowledge [18]. It is negatively correlated with conscientiousness personality, agreeableness personality, open personality and extroverted personality. The reason may be that the conscientiousness personality is measured, the agreeableness personality is humble, the open personality is active, and the extroverted personality is enthusiastic about communication [19].
