Hi yundian,

Thanks for giving us the link, can you try adding this CSS code in Quick CSS, located in Enfold > General Styling:

#h1.main-title.entry-title {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    width: 450px;
    max-width: 100%;
}

Just adjust the width value.
Hope this helps.

Best regards,
Nikko
