How does the Sun appear in a natal chart?

The sun represents core will, vitality, self-identity, creativity and the direction a person wants to develop. It is not as instinctive as the moon, nor as immediately visible as the rising; the sun is more like a center that needs to be consciously, chosen, and continually developed.

So the sun sign is not the complete personality. It answers: In what way is my life force illuminated? In what way do I want to affirm my existence?

When the sun sets in the fire sign, the core will needs more action, heat and direction; when the earth sign falls, it needs more realistic results, stability and sustainability; when the sun falls in the wind sign, it needs more understanding, connection and concepts; when it falls in the water sign, it needs emotion, memory, resonance and depth.

But sitting is just style. A Leo Sun may not necessarily be outgoing, a Capricorn Sun may not necessarily just want to work, and a Pisces Sun may not necessarily be weak. Continue to look at the placement of houses and aspects.

The Sun in the house indicates in which area of life the core will develops. When the Sun is in the 5th house, creativity, self-expression, love, and being seen are more important; when it is in the 10th house, career, achievement, social role, and public identity are more important; when it is in the 12th house, the Sun is more introverted and needs solitude, behind-the-scenes space, healing, or a spiritual outlet.

For the same sun sign but in different houses, the life experience will be much different.

The Sun conjunct Saturn will bring responsibility, restraint, and time pressure to self-development; the Sun square Neptune may make self-identity more vague, idealistic, or need an outlet for inspiration; the Sun trine Jupiter will amplify beliefs, opportunities, and a sense of growth; the Sun conjunct Pluto will bring strong transformation and power issues to self-development.

Aspects explain why the same sun sign looks completely different in different people.

Open the natal chart and look at the sun sign, solar house position, solar phase, whether the sun is an important house lord in order, and whether the current transit triggers the sun. When reading the sun, you must at least be able to explain "what style it uses, which field it is in, and which planets it is affected by."
