It is not recommended to do it yourself, which will cause problems. Just find a professional institution, the Chinese Testament Library.

Let me give you some examples.

1, have you written a will? Do you know how to write? Most people in China have never written a will, or even can't read it at all. Court trial data show that 60% of the cases handled are invalid, and one in every two cases is invalid.

Did you write down where you put it? Are you sure the heir got the will in the first place? No matter how well written it is, it will be zero if it is not well kept, and the contents of the will will will be exposed in advance, causing new family conflicts and no peace in old age.

3. How do you prove that you wrote clearly? There will be disputes in the future. It costs a lot of money to fight a lawsuit. If you fight for a few years, the heir will be bored to death. You also need to prove that your mind is clear, your handwriting is clearly identified, and you wrote it yourself, because the words written in each period are different and there are many pits.

To sum up, don't give up on yourself, just find a professional and reliable organization to do it.
