For individuals born in the Year of the Snake in 1977， it is believed that they will encounter three major劫难 (jié nàn， tribulations) in their lifetime， according to Chinese astrology. These challenges often occur around the ages of 36， 48， and 55 (calculated by 周岁， or actual age).

Here's a breakdown of the potential tribulations:

Age 36: Marriage Crisis At this age， marital problems may arise， especially for men. There may be an increase in extramarital affairs， potentially leading to divorce. These marital issues can also negatively impact career advancement， particularly for those in government or public institutions， potentially causing a setback in their careers.

Age 48: Economic Hardship/Career Setbacks: As 48 is their 本命年 (běn mìng nián， zodiac year)， people may face financial difficulties due to unforeseen events that deplete their savings. This can cause significant economic pressure and emotional distress. In their career， they may encounter significant setbacks such as project failures or job changes that negatively impact their professional life. It's a time when they may feel psychologically pressured， doubt their abilities， and feel uncertain about the future.

Age 55: Health Problems: Health issues may surface around this age. Those who had busy， unhealthy lifestyles in their younger years may be prone to serious illnesses， including the risk of cancer. It is crucial to pay attention to bodily changes and undergo regular health check-ups.

In addition to these age-related tribulations， there may be other challenges:

Relationship Issues: People may experience interpersonal issues， struggling to express themselves and connect with others.
