1. Do not modify or use the trademark at will. (Including color, overall proportion, addition or deletion of a certain part, font, etc.)
2. Pay attention to the issue of trademark renewal at any time (trademarks are renewed once every ten years. If you miss the renewal grace period, it will become invalid. )
3. Do not use the same or similar trademark as the trademark (it can easily cause trademark infringement)
4. Do not use the trademark in unregistered categories (it can easily be in vain) Kung Fu)
