Can the logo of Haval h3 be changed into letters?

Changing the letterhead is not a modification. This behavior is like putting your favorite slogan or pattern on your car. Illegal modification is indeed prohibited in China, but this change of stationery is not a modification at all, so it is not illegal. Although there are restrictions on modification in China at present, it is not completely prohibited. For example, "changing oil to gas" is still open in China.
