add to Home > Design > Custom CSS

/* Hide current site title */
body#collection-5ddbfbb91d73d900345cf07f .Header-branding {
    visibility: hidden;
}
/* Set new title */
body#collection-5ddbfbb91d73d900345cf07f .Header-branding:before {
    content: "My name is Tuan";
    visibility: visible;
    font-size: 20px;
    color: red;
}

replacing body#....7f with Page ID. Each page will have different ID. See my signature to know how to find Page ID.
