Generally speaking, lawyers' income is relatively low at the initial stage of their career, and will gradually increase with the accumulation of work experience and the improvement of their professional ability.

However, this is only an estimate, and the actual income will vary due to personal ability, industry situation and economic environment. The lawyer's income is also influenced by the internal salary structure and reward system of the law firm, so the specific income situation needs specific analysis.

please note that the above is only a general answer, and the specific income may be different due to personal situation and industry development. It is suggested that you consult Hangzhou Tianbook Law Firm or related professionals to obtain more accurate information.
