以下是修改后的代码：

while(1) {
    OLED_Clear();
    OLED_ShowString(0,30,"21221054",16);
    OLED_ShowString(0,15,"2023/5/18",16);
    OLED_ShowChinese(0,0,0,16,1);
    OLED_ShowChinese(16,0,1,16,1);
    OLED_ShowChinese(32,0,2,16,1);
    for(j=0;j<8;j++) {
        OLED_ShowChinese(j * 16, 0, point[scroll_pos + j], 16, 1);
    }
    OLED_Refresh_Gram();
    delay_ms(SCROLL_SPEED);
    if (scroll_dir == 0){
        scroll_pos++;
        if (scroll_pos + 8 >= SIZE) {
            scroll_dir = 1;
            scroll_pos = SIZE - 8;
        }
    }else{
        scroll_pos--;
        if (scroll_pos == 0) {
            scroll_dir = 0;
            scroll_pos = 0;
        }
    }
}

主要修改如下：
- 在for循环中，将横坐标从 `64 + j * 16` 改为 `j * 16`，使其从左往右滚动。
- 在每次滚动时，将字体的横坐标改为 `j * 16`，使其从左往右滚动。

注意，修改后的代码可能需要根据具体情况进行调试和修改。
