Buddhism basically died out in India proper a long time ago.
Well, first of all, the very few native Indians that I know who called themselves Buddhists were converts from Hinduism because they belonged to the lowest caste. What I have been able to discern from them is that they still basically practise Hinduism but without the caste taboo or getting blessings from the Brahmin priests. They sort of pray to Buddha as if the Buddha was a reincarnation of Krishna.

佛教在很久以前就在印度消失了。
首先,我所知道的极少数自称佛教徒的印度原住民是从印度教皈依的,因为他们属于最低种姓。我能从他们身上看出的是,他们基本上仍然奉行印度教,但没有种姓禁忌,也没有得到婆罗门祭司的祝福。他们向佛陀祈祷,好像佛陀是奎师那的转世。
(译注:奎师那,是印度教诸神中最广受崇拜的一位神祇,被视为毗湿奴的第八个化身,是诸神之首,世界之主。)

But I am told that in the South of India, that those who are converted from Hinduism and are educated practise Theravada Buddhism, which is the official religion in Sri Lanka for the Singhalese there, and is the Buddhist tradition in Myanmar, Thailand, Laos and Cambodia.

但我听说,在印度南部,那些从印度教皈依并接受教育的人都信奉小乘佛教,这是斯里兰卡僧伽罗人的官方宗教,也是缅甸、泰国、老挝和柬埔寨的佛教传统。

The main difference between Theravada Buddhism as against Mahayana Buddhism is that with Theravada it is monks or elders led and is about self liberation; whereas with Mahayana it is more a lay practice led by what we call the Bodhisattva vow and is about universal liberation of all sentient beings.

小乘佛教与大乘佛教的主要区别在于,小乘佛教是僧侣或长老领导的,是关于自我解放的;而大乘佛教更多的是由我们所谓的菩萨誓言引导的世俗修行,是关于众生的普遍解脱。

In North of India, near Nepal or Sikkim or Tibet, the Indian Buddhists practise Mahayana Buddhism that is closer to Tibetan Vajrayana Buddhism with a mix of Hindu folklore. Vajrayana Buddhism is sort of Mahayana +++. Mahayana has philosophical and psychological doctrines of spiritual logic and rationale but Vajrayana has in addition physiological and cosmological doctrines as well. Further, instead of just meditation as yoga in Mahayana, you have in addition, visualisation yoga and recitation yoga in the Vajrayana. In a broad sense Vajrayana is a higher or more developed tertiary form of Buddhism.

在印度北部,靠近尼泊尔、锡金或西藏的地方,印度佛教徒奉行大乘佛教,更接近西藏金刚乘佛教,混合了印度民间传说。金刚乘佛教有点像大乘佛教。大乘佛教有精神逻辑和基本原理的哲学和心理学说,而金刚乘佛教也有生理和宇宙学说。此外,在大乘佛教,你不仅有冥想瑜伽,还有金刚佛教的观想瑜伽和背诵瑜伽。广义上说,金刚乘是佛教的一种更高或更发达的三级形式。

Now, Mahayana Buddhism is practised in Vietnam, China, Taiwan, Korea and Japan.
So Chinese Buddhism is Mahayana. There are various Mahayana schools in China but essentially there are 2 main schools - Zen and Buddha devotion.

现在,大乘佛教在越南、中国、中国台湾、韩国和日本都有实践。
所以中国佛教是大乘佛教。中国有很多大乘佛教流派,但主要有两大流派——禅宗和佛陀信仰。

Zen is sort of like Karma Yoga where you strive for ‘sudden awakening’ followed by ‘gradual cultivation’ to identify with the Absolute that is the transcendental supramundane Buddha and you focus on the three main doctrines of ‘Sunyata’, ‘Not-Self’ and ‘Mind-Consciousness only’ to lead you to the Tathagharba or Thusness that is the Primordial Mind-Consciousness (sort of Brahma as just pure luminous mind in total eternal bliss).

禅宗有点像因果报应瑜伽,你努力“突然觉醒”,然后“逐步修炼”,以认同超世俗的绝对佛陀,你专注于“空性”的三大教义,“非我”和“心意识”引导你进入如来或修行,也即原始心灵意识(类似于梵天,纯粹光明的心在完全永恒的幸福中)。

Buddha devotion is sort of like Bhakti Yoga where you chant and think of your nominated Buddha in devotion e.g. Amitabha Buddha in everything you think, say or do. Instead of aspiring to be like Buddha you have Buddha coming to you, as you have given yourself totally, mind, heart and soul to Buddha.

佛陀信仰有点像巴克提瑜伽,你吟诵并虔诚地想起你指定的佛陀。例如,阿弥陀佛就是你所想、所说、所做的一切。当你把自己全部的思想、心、灵魂都给了佛陀,佛陀就会来到你身边,而不是渴望成为佛陀。

Most Chinese Buddhists are into Buddha devotion (almost 95%) and only the educated, Iearned and the erudite will follow Zen. Most just want to live their normal lives and basically do the daily ‘puja’ of devotion, instead of joining a sort of ashram to learn how to meditate properly and learn the arcane scxtures etc - just too hard, when you have a family, friends and business!
Of course it is very much more complicated than that but here we are just pointing out the key differences.
Nobody Going Nowhere

大多数中国佛教徒都皈依佛祖(几乎95%),只有受过教育的、有学问的和博学的人才会皈依禅宗。大多数人只想过正常的生活,基本上每天都做虔诚的“礼拜”,而不是参加一种道场来学习如何正确地冥想和学习神秘的经文等等——当你有家庭、朋友和生意的时候,这太难了!
当然,实际情况要比这复杂得多,但这里我们只是指出关键的区别。
没有人走投无路。
