Three small fixes: "came to my home" needs the preposition "to." "Long time no see" is actually a fun informal expression in English, but it's used as a greeting directly to someone — "long time no see!" Since you're talking about your grandmother, we'd say "it's been a long time since I've seen her." And for weather we say "it's windy" or "it's really windy" rather than "today is strong wind." Hope you're enjoying the visit! 😊
